    The complex Wishart ensemble is the statistical ensemble
    of $M \times N$ complex random matrices with $M \geq N$
    such that the real and imaginary parts of each element
    are given by independent standard normal variables.
    The Marcenko--Pastur (MP) density $\rho(x; r), x \geq 0$
    describes the distribution for squares of the
    singular values of the random matrices in this ensemble
    in the scaling limit $N \to \infty$, $M \to \infty$ with
    a fixed rectangularity $r=N/M \in (0, 1]$.
    The dynamical extension of the squared-singular-value distribution
    is realized by the noncolliding squared Bessel process,
    and its hydrodynamic limit provides the
    two-parametric MP density $\rho(x; r, t)$ with time $t \geq 0$,
    whose initial distribution is $\delta(x)$.
    Recently, Blaizot, Nowak, and Warcho{\l}
    studied the time-dependent complex Wishart ensemble
    with an external source and introduced
    the three-parametric MP density
    $\rho(x; r, t, a)$ by analyzing the
    hydrodynamic limit of the process starting from $\delta(x-a), a > 0$.
    In the present paper, we give useful expressions
    for $\rho(x; r, t, a)$ and perform a systematic study
    of dynamic critical phenomena
    observed at the critical time $t_{\rm c}(a)=a$ when $r=1$.
    The universal behavior in the long-term limit
    $t \to \infty$ is also reported.
    It is expected that the present system having
    the three-parametric MP density provides
    a mean-field model for QCD
    showing spontaneous chiral symmetry breaking.

  • Switching particle systems for foraging ants showing phase transitions in path selections Reviewed

    Switching interacting particle systems studied in probability theory are the stochastic processes of hopping particles on a lattice made up of slow and fast particles, where the switching between these types of particles occurs randomly at a given transition rate. This paper explores how such stochastic processes involving multiple particles can model group behaviors of ants. Recent experimental research by the last author’s group has investigated how ants switch between two types of primarily relied cues to select foraging paths based on the current situation. Here, we propose a discrete-time interacting random walk model on a square lattice, incorporating two types of hopping rules. Numerical simulation results demonstrate global changes in selected homing paths, transitioning from trailing paths of the ‘pheromone road’ to nearly optimal paths depending on the switching parameters. By introducing two types of order parameters characterizing the dependence of homing duration distributions on switching parameters, we discuss these global changes as phase transitions in ant path selections. We also study critical phenomena associated with continuous phase transitions.

    a smooth, compact Riemannian manifold $(M,g)$
    and the determinantal point process $\xila$ on $M$ associated with the spectral
    projection of $-\Delta_g$ onto the subspace corresponding to the eigenvalues up to
    $\la^2$.
    We show that the pull-back of $\xila$ by the exponential map

    weakly to the universal determinantal point process on
    $T_p^* M$ as $\la \to \infty$.

    The Ginibre point process is given by the eigenvalue
    distribution of a non-hermitian complex Gaussian matrix
    in the infinite matrix-size limit.
    This is a determinantal point process (DPP) on the complex
    plane $\C$ in the sense that all correlation functions
    are given by determinants specified by an integral
    kernel called the correlation kernel.
    Shirai introduced the one-parameter
    ($m \in \N_0$) extensions of the Ginibre DPP
    and called them
    the Ginibre-type point processes.
    In the present paper we consider a generalization
    of the Ginibre and the Ginibre-type point processes on $\C$
    to the DPPs in the higher-dimensional spaces,
    $\C^D, D=2,3, \dots$, in which
    they are parameterized by a multivariate level
    $m \in \N_0^D$.
    We call the obtained point processes
    the extended Heisenberg family of DPPs,
    since the correlation kernels are generally
    identified with the correlations of two points in
    the space of Heisenberg group expressed by
    the Schr\"{o}dinger representations.
    We prove that all DPPs in this large family are
    in Class I of hyperuniformity.

    We study the hydrodynamic limits of three kinds of one-dimensional stochastic log-gases known as Dyson's Brownian motion model, its chiral version, and the Bru-Wishart process studied in dynamical random matrix theory. We define the measure-valued processes so that their Cauchy transforms solve the complex Burgers-type equations. We show that applications of the method of characteristic curves to these partial differential equations provide the functional equations relating the Cauchy transforms of measures at an arbitrary time with those at the initial time. We transform the functional equations for the Cauchy transforms to those for the R-transforms and the S-transforms of the measures, which play central roles in free probability theory. The obtained functional equations for the R-transforms and the S-transforms are simpler than those for the Cauchy transforms and useful for explicit calculations including the computation of free cumulant sequences. Some of the results are argued using the notion of free convolutions.

    A determinantal point process (DPP) is an ensemble of random nonnegative-integer-valued Radon measures [Formula: see text] on a space S with measure [Formula: see text], whose correlation functions are all given by determinants specified by an integral kernel K called the correlation kernel. We consider a pair of Hilbert spaces, [Formula: see text], which are assumed to be realized as [Formula: see text]-spaces, [Formula: see text], [Formula: see text], and introduce a bounded linear operator [Formula: see text] and its adjoint [Formula: see text]. We show that if [Formula: see text] is a partial isometry of locally Hilbert–Schmidt class, then we have a unique DPP [Formula: see text] associated with [Formula: see text]. In addition, if [Formula: see text] is also of locally Hilbert–Schmidt class, then we have a unique pair of DPPs, [Formula: see text], [Formula: see text]. We also give a practical framework which makes [Formula: see text] and [Formula: see text] satisfy the above conditions. Our framework to construct pairs of DPPs implies useful duality relations between DPPs making pairs. For a correlation kernel of a given DPP our formula can provide plural different expressions, which reveal different aspects of the DPP. In order to demonstrate these advantages of our framework as well as to show that the class of DPPs obtained by this method is large enough to study universal structures in a variety of DPPs, we report plenty of examples of DPPs in one-, two- and higher-dimensional spaces S, where several types of weak convergence from finite DPPs to infinite DPPs are given. One-parameter ([Formula: see text]) series of infinite DPPs on [Formula: see text] and [Formula: see text] are discussed, which we call the Euclidean and the Heisenberg families of DPPs, respectively, following the terminologies of Zelditch.

    Miller and Sheffield introduced the notion of
    an imaginary surface as an equivalence class
    of pairs of simply connected proper subdomains of
    $\C$ and Gaussian free fields (GFFs)
    on them under the conformal equivalence.
    They considered the situation in which
    the conformal transformations are given by
    a chordal Schramm--Loewner evolution (SLE).
    In the present paper, we construct
    GFF-valued processes on $\H$ (the upper half-plane)
    and $\O$ (the first orthant of $\C$)
    by coupling a GFF with a multiple SLE evolving in time on each domain.
    We prove that a GFF on $\H$ and $\O$ is (locally) coupled
    with a multiple SLE if the multiple SLE is driven
    by a stochastic log-gas called the Dyson model defined
    on $\R$ and the Bru--Wishart process
    defined on $\R_+$, respectively.
    We obtain pairs of time-evolutionary domains
    with multiple-slits and GFF-valued processes.

    The present paper is concerned with properties of multiple Schramm–
    Loewner evolutions (SLEs) labelled by a parameter κ ∈ (0, 8]. Specifically, we consider
    the solution of the multiple Loewner equation driven by a time change of Dyson’s
    Brownian motions in the non-colliding regime. Although it is often considered that
    several properties of the solution can be studied by means of commutation relations
    of SLEs and the absolute continuity, this method is available only in the case that the
    curves generated by commuting SLEs are separated. Beyond this restriction, it is not
    even obvious that the solution of the multiple Loewner equation generates multiple
    curves. To overcome this difficulty, we employ the coupling of Gaussian free fields and
    multiple SLEs. Consequently, we prove the longstanding conjecture that the solution
    indeed generates multiple continuous curves. Furthermore, these multiple curves are
    (i) simple disjoint curves when κ ∈ (0, 4], (ii) intersecting curves when κ ∈ (4, 8), and
    (iii) space-filling curves when κ = 8.

    The most studied continuum percolation model in two dimensions is the Boolean model consisting of disks with the same radius whose centers are randomly distributed on the Poisson point process (PPP). We also consider the Boolean percolation model on the Ginibre point process (GPP) which is a typical repelling point process realizing hyperuniformity. We think that the PPP approximates a disordered configuration of individuals, while the GPP does a configuration of citizens adopting a strategy to keep social distancing in a city in order to avoid contagion. We consider the SIR models with contagious infection on supercritical percolation clusters formed on the PPP and the GPP. By numerical simulations, we studied dependence of the percolation phenomena and the infection processes on the PPP- and the GPP-underlying graphs. We show that in a subcritical regime of infection rate the PPP-based models show emergence of infection clusters on clumping of points which is formed by fluctuation of uncorrelated Poissonian statistics. On the other hand, the cumulative numbers of infected individuals in processes are suppressed in the GPP-based models.

    The bulk scaling limit of eigenvalue distribution
    on the complex plane ${\mathbb{C } }$
    of the complex Ginibre random matrices provides
    a determinantal point process (DPP).
    This point process is a typical example of
    disordered hyperuniform system characterized
    by an anomalous suppression of large-scale
    density fluctuations.
    As extensions of the Ginibre DPP, we consider
    a family of DPPs defined on the $D$-dimensional
    complex spaces ${\mathbb{C } }$, $D \in {\mathbb{N } }$, in which
    the Ginibre DPP is realized when $D=1$.
    This one-parameter family ($D \in {\mathbb{N } }$) of DPPs
    is called the Heisenberg family,
    since the correlation kernels are
    identified with the Szeg\H{o} kernels for the
    reduced Heisenberg group.
    For each $D$, using the modified Bessel functions,
    an exact and useful expression
    is shown for the local number variance
    of points included in a ball with radius $R$
    in ${\mathbb{R } }^{2D} \simeq {\mathbb{C } }^D$.
    We prove that any DPP in the Heisenberg family is in the
    hyperuniform state of Class I,
    in the sense that the number variance
    behaves as $R^{2D-1}$ as $R \to \infty$.
    Our exact results provide asymptotic expansions
    of the number variances in large $R$.

    The unitary group with the Haar probability measure
    is called Circular Unitary Ensemble.
    All the eigenvalues lie on the unit
    circle in the complex plane and they can be regarded as a
    determinantal point process on ${\mathbb{S } }^1$.
    It is also known that
    the scaled point processes converge weakly to the determinantal point
    process associated with the so-called sine kernel
    as the size of matrices tends to $\infty$.
    We extend this result to the case of high-dimensional spheres
    and show that the scaling limit processes are determinantal
    point processes associated with the kernels expressed by the
    Bessel functions of the first kind.

    We introduce new families of determinantal point processes (DPPs)<br />
    on a complex plane ${\mathbb{C } }$, which are classified into seven types<br />
    following the irreducible reduced affine root systems,<br />

    Their multivariate probability densities are doubly periodic<br />
    with periods $(L, iW)$, $0 &lt; L, W &lt; \infty$, $i=\sqrt{-1}$.<br />
    The construction is based on the orthogonality relations <br />

    $[0, L) \times i [0, W)$, which are proved in this paper <br />
    for the $R_N$-theta functions introduced by Rosengren and Schlosser.<br />
    In the scaling limit $N \to \infty, L \to \infty$<br />

    $\rho=N/(LW)$ and constant $W$, we obtain four types of<br />
    DPPs with an infinite number of<br />
    points on ${\mathbb{C } }$, which have periodicity with period $i W$. <br />
    In the further limit $W \to \infty$ with constant $\rho$,<br />
    they are degenerated into three infinite-dimensional DPPs.<br />
    One of them is uniform on ${\mathbb{C } }$ and equivalent <br />
    with the Ginibre point process<br />
    studied in random matrix theory, while<br />
    other two systems are rotationally symmetric around the origin,<br />
    but non-uniform on ${\mathbb{C } }$.<br />
    We show that the elliptic DPP<br />
    of type $A_{N-1}$ is identified with the particle section,<br />
    obtained by subtracting the background effect, <br />
    of the two-dimensional exactly solvable model<br />

    Relationship to the Gaussian free field on a torus<br />

    Recently del Monaco and Schlei{\ss}inger addressed <br />
    an interesting problem whether one can take the limit of<br />
    multiple Schramm--Loewner evolution (SLE) <br />
    as the number of slits $N$ goes to infinity.<br />
    When the $N$ slits grow from points on the real line $\R$<br />
    in a simultaneous way and go to infinity<br />
    within the upper half plane $\H$,<br />
    an ordinary differential equation <br />
    describing time evolution of the conformal map $g_t(z)$<br />
    was derived in the $N \to \infty$ limit, <br />
    which is coupled with a complex Burgers equation<br />
    in the inviscid limit. <br />
    It is well known that the complex Burgers equation<br />
    governs the hydrodynamic limit of the Dyson model<br />
    defined on $\R$ studied in random matrix theory, <br />
    and when all particles start from<br />
    the origin, the solution of this Burgers equation is given<br />
    by the Stieltjes transformation of the measure which<br />
    follows a time-dependent version of Wigner&#039;s semicircle law.<br />
    In the present paper, first we study the hydrodynamic limit<br />
    of the multiple SLE in the case that all <br />
    slits start from the origin. <br />
    We show that the time-dependent version of Wigner&#039;s <br />
    semicircle law determines the time evolution<br />
    of the SLE hull, $K_t \subset \H\cup \R$ ,<br />
    in this hydrodynamic limit. <br />
    Next we consider the situation such that <br />
    a half number of the slits start from $a&gt;0$ and<br />
    another half of slits start from $-a &lt; 0$,<br />
    and determine the multiple SLE in the <br />
    hydrodynamic limit. <br />
    After reporting these exact solutions,<br />
    we will discuss the universal long-term behavior of <br />
    the multiple SLE and its hull $K_t$ in the hydrodynamic limit.

    We consider the vicious walker model, which was introduced by Michael Fisher in his Boltzmann medal lecture in 1983 as a mathematical model of wetting and melting phenomena. It is a system of particles performing noncolliding random walk in one dimension. Using nonintersecting property of the paths of vicious walkers and by elementary calculus of deter minants, we show that the Green function of the system is equal to the Schur function, which plays an important role in the representation theory of symmetric group, and its two kinds of determinantal expressions are derived. MacMahon conjecture, Bender-Knuth conjecture and Macdonald equality for the summations of Schur functions are discussed from the viewpoint of vicious walker model. By taking the diffusion scaling limit of the vicious walker model, a system of noncolliding Brownian particles is constructed and its relation to the distribution of eigenvalues of real symmetric random matrices is clarified.

  • Elliptic Extensions in Statistical and Stochastic Systems Reviewed

    Makoto Katori（ Role： Sole authorall pages (pp.125)）

    Hermite's theorem makes it known that there are three levels of mathematical frames in which a simple addition formula is valid. They are rational, q-analogue, and elliptic-analogue. Based on the addition formula and associated mathematical structures, productive studies have been carried out in the process of q-extension of the rational (classical) formulas in enumerative combinatorics, theory of special functions, representation theory, study of integrable systems, and so on. Originating from the paper by Date, Jimbo, Kuniba, Miwa, and Okado on the exactly solvable statistical mechanics models using the theta function identities (1987), the formulas obtained at the q-level are now extended to the elliptic level in many research fields in mathematics and theoretical physics. In the present monograph, the recent progress of the elliptic extensions in the study of statistical and stochastic models in equilibrium and nonequilibrium statistical mechanics and probability theory is shown. At the elliptic level, many special functions are used, including Jacobi's theta functions, Weierstrass elliptic functions, Jacobi's elliptic functions, and others. This monograph is not intended to be a handbook of mathematical formulas of these elliptic functions, however. Thus, use is made only of the theta function of a complex-valued argument and a real-valued nome, which is a simplified version of the four kinds of Jacobi's theta functions. Then, the seven systems of orthogonal theta functions, written using a polynomial of the argument multiplied by a single theta function, or pairs of such functions, can be defined. They were introduced by Rosengren and Schlosser (2006), in association with the seven irreducible reduced affine root systems. Using Rosengren and Schlosser's theta functions, non-colliding Brownian bridges on a one-dimensional torus and an interval are discussed, along with determinantal point processes on a two-dimensional torus. Their scaling limits are argued, and the infinite particle systems are derived. Such limit transitions will be regarded as the mathematical realizations of the thermodynamic or hydrodynamic limits that are central subjects of statistical mechanics.

    The non-Hermitian matrix-valued Brownian motion (BM)
    is the stochastic process of a random matrix
    whose entries are given by independent complex BMs.
    At each time, the matrix is non-normal and is not
    unitarily diagonalizable.
    In order to diagonalize the matrix, we have to
    construct the similarity transformation
    by determining the left- and right-eigenvectors
    to satisfy the bi-orthonormality relation.
    By It\^o's formula, we have shown such non-normality
    implies that the eigenvalue process
    on $\mathbb{C}$ is coupled with the eigenvector-overlap
    process.
    In other words, the eigenvalue point process on $\mathbb{C}$
    is coupled with other marked point processes
    weighted by the eigenvector-overlaps.
    For such a coupled system, we have considered two approaches.
    One of them is based on the regularized
    Fuglede--Kadison determinant of the matrix.
    This stochastic field should be considered not on
    $\mathbb{C}$ but in $\mathbb{C}^2$.
    Another approach is based on the stochastic
    partial differential equations (SPDEs) for the pairing
    of the (marked) point processes and proper test functions.
    There the SPDEs exhibit a hierarchical structure.
    We also consider the process
    starting from non-diagonalizable matrices.
    In such cases, the Jordan block decomposition becomes
    important and this structure creates
    domains on $\mathbb{C}$, which are called
    the pseudospectra. They are not exact spectra
    but there the resolvent of matrix takes extremely large values.
    Then the coupling between the eigenvalue process
    and the pseudospectrum process should be studied.
    We will report our trials to characterize the
    non-Hermitian matrix-valued BM and
    list out the open problems which have not appeared
    in the previous study on the Hermitian matrix-valued BM
    and its eigenvalue process known as Dyson's BM.

  • Pseudospectrum dynamics in relaxation processes from far-from-normal to near-normal matrices Invited International conference

    We consider nonnormal matrix-valued dynamical systems
    with discrete time.
    For an eigenvalue of matrix,
    the number of times it appears as a root of
    the characteristic polynomial is called the
    algebraic multiplicity.
    On the other hand,
    the geometric multiplicity is the dimensionality
    of the linear space of eigenvectors associated
    with that eigenvalue.
    If the former exceeds the latter,
    then the eigenvalue is defective
    and the matrix becomes nondiagonalizable
    by any similarity transformation.
    The discrete-time of our dynamics is identified with
    the geometric multiplicity of the zero eigenvalue
    $\lambda_0=0$.
    Its algebraic multiplicity
    takes about half of the matrix size at $t=1$
    and increases stepwise in time, which keeps
    excess to the geometric multiplicity until
    their coincidence at the final time.
    We study the relaxation processes from
    far-from-nonnomal to near-normal matrices.
    We show that such processes are well described by
    the dynamics of pseudospectrum
    containing $\lambda_0$,
    whose defectivity is recovering in time.
    Here the pseudospectra are the domains
    on the complex plane which are not necessarily
    exact spectra but in which the resolvent
    of matrix takes extremely large values.
    By constructing generalized eigenspace for
    $\lambda_0$, we give the Jordan block
    decomposition for the resolvent of matrix
    and characterize the pseudospectrum dynamics.
    Separation and dilatation of the symbol curves
    of the corresponding Toeplitz operators are
    observed in the pseudospectrum around $\lambda_0$.
    The matrix-size dependence is also studied.
    We hope that the present study will help
    us to understand the eigenvalue and
    eigenvector-overlap processes
    of non-Hermitian matrix-valued
    stochastic processes started from
    nonnormal and defective matrices.

  • Elliptic Extensions in Statistical and Stochastic Systems Invited International conference

    Random Media and Random Fields  ( Leiden University )   2024.8  Lorentz Center

    We will report the recent progress
    of the elliptic extensions in the study of statistical and
    stochastic models in
    equilibrium and nonequilibrium statistical mechanics and
    probability theory.
    We construct two groups of
    interacting particle systems
    using the seven families of
    theta functions with integer labels, which were
    introduced by Rosengren and Schlosser (2006)
    in association with the Macdonald denominators
    (the elliptic extensions of the Weyl denominators)
    of the seven irreducible reduced affine root systems.
    There the integer label indicates
    the total number of particles in each system.
    The first group of systems consists of seven kinds of
    noncolliding Brownian bridges on a circle or an interval,
    and the second one
    of seven kinds of determinantal point processes
    (DPPs) on a two-dimensional torus.
    The former systems are $(1+1)$-dimensional stochastic
    processes and the latter ones are statistical models of
    stationary point configurations in two dimensions,
    both of which provide mathematical models for
    fermion systems with repulsive interactions.
    The boundary conditions
    and the initial/final configurations
    of the noncolliding Brownian bridges,
    and the periodicity conditions of the DPPs are systematically
    changed depending on the choice of
    the root system from the seven types.
    We argue the scaling limits and precisely define
    the infinite particle systems.
    The connections to other statistical systems
    such as the one-component plasma models
    and the Gaussian free fields will be also discussed.
    The present talk is based on a recently published booklet,

    and Stochastic Systems},
    SpringerBriefs in Mathematical Physics 47,
    Springer (2023).

    The non-Hermitian matrix-valued Brownian motion (BM)
    is the stochastic process of a random matrix
    whose entries are given by independent complex BMs.
    We consider a one-parameter extension of this process,
    which can be regarded as a dynamical version
    of Girko's elliptic ensemble interpolating
    the GUE and the Ginibre ensemble of random matrices.
    Notice that the eigenvalue process of GUE is known as
    Dyson's BM.
    For each process in this family,
    the bi-orthogonality relation is imposed between
    the left and the right eigenvector processes, which allows for
    the scale-transformation invariance of the system.
    There each eigenvalue process is coupled with
    the eigenvector-overlap process which is a
    Hermitian matrix-valued process with entries given by
    products of overlaps of the left and the right eigenvectors.
    Time-evolutionary point processes (PPs) of eigenvalues
    and the marked PPs weighted by the elements of
    eigenvector-overlap processes are introduced.
    We study the stochastic equations for the pairings of
    these PPs and proper test functions.
    This talk is based on the joint work with
    Syota Esaki (Oita), Satoshi Yabuoku (Kitakyushu),
    and Jacek Ma{\l}ecki (Wroc{\l}aw).

    The eigenvector-overlap process is a
    Hermitian matrix-valued process,

    We derive a set of SDEs
    for the coupled system of the eigenvalue process and the
    eigenvector-overlap process and
    discuss the results from the viewpoint of
    condition numbers.
    The regularized Fuglede--Kadison (FK) determinant
    is introduced which evolves following a stochastic PDE
    on the two-dimensional complex space.
    Time-dependent point process of eigenvalues
    and its variation marked by the squares of
    the condition numbers are
    related to the logarithmic derivatives of the
    FK-determinant random-field.
    We also discuss the pseudospectrum process
    in the case that the initial matrix is nonnormal.

    The non-Hermitian matrix-valued Brownian motion
    is the stochastic process of a random matrix
    whose entries are given by independent complex Brownian motions.
    The bi-orthogonality relation is imposed between
    the right and the left eigenvector processes, which allows for
    their scale transformations with an invariant eigenvalue process.
    The eigenvector-overlap process is a
    Hermitian matrix-valued process,
    each element of which is given by
    a product of an overlap of right eigenvectors
    and that of left eigenvectors.
    We derive a set of stochastic differential equations (SDEs)
    for the coupled system of the eigenvalue process and the
    eigenvector-overlap process and prove
    the scale-transformation invariance of the obtained SDE system.
    The Fuglede--Kadison (FK) determinant associated with the present
    matrix-valued process is regularized by introducing
    an auxiliary complex variable. This variable is necessary
    to give the stochastic partial differential equations (SPDEs)

    We consider a one-parameter family of
    non-Hermitian matrix-valued processes,
    which can be regarded as a dynamical extension
    of Girko's ensemble interpolating
    the GUE and the Ginibre ensemble of random matrices.
    For each process in this family,
    the bi-orthogonality relation is imposed between
    the right and the left eigenvector processes, which allows for
    the scale-transformation invariance of the system.
    There each eigenvalue process is coupled with
    the eigenvector-overlap process, which is a
    Hermitian matrix-valued process with entries given by
    products of overlaps of the right and left eigenvectors.
    The Fuglede--Kadison (FK) determinants of
    the present matrix-valued processes
    are regularized by introducing an auxiliary complex variable.
    Then, associated with the regularized FK determinants,
    the time-dependent random fields
    are defined in the two-dimensional complex space
    and their stochastic partial differential
    equations (SPDEs) are derived.
    Time-dependent point processes of eigenvalues
    and their variations weighted by the diagonal elements of
    the eigenvector-overlap processes are
    related to the logarithmic derivatives of the
    regularized FK-determinant random-fields.
    We also discuss the PDEs obtained by averaging the SPDEs.

    Multiple extensions of Schramm--Loewner evolution (SLE)
    have been usually studied by the method using
    commutation relations of SLEs and the absolute continuity of measures.
    This method is, however, available only in the case such that
    the curves generated by commuting SLEs are separated from each other.
    Recently we have found that this restriction can be removed if
    we impose the coupling between the multiple SLEs and the appropriately
    modified Gaussian free fields (GFFs), where we have followed the
    work by Dub\'edat, Sheffield, Miller, and others on the coupling
    of a single SLE and GFF.
    By It\^o's stochastic calculus, we prove that proper couplings
    between multiple SLEs and GFFs are established if and only if
    the driving processes of multiple SLEs are of
    a specified type of interacting particle systems.
    They are identified with the log-gases extensively studied as
    dynamical extensions of the eigenvalue distributions
    in random matrix ensembles.
    We will show that this new connection between SLE and
    random matrix theory (RMT) enables us to enjoy variety of
    coupled systems due to the variety of ensembles in RMT.
    The law of large numbers are then clarified
    as the Wigner semicircle law and its variations in the RMT level
    and as the Loewner chains driven by
    the processes solving the Burgers-type PDEs
    in the SLE level.

    The non-Hermitian matrix-valued Brownian motion (BM) induces
    a coupled system of the eigenvalue process
    and the eigenvector-overlap process.
    Here the eigenvector-overlap process
    is a matrix-valued process, each element of which
    is given by a product of an overlap of right eigenvectors
    and that of left eigenvectors.
    We consider
    the time-dependent random field defined on the two-dimensional
    complex space using the notion of
    the reguralized Fuglede--Kadison determinant
    of the matrix-valued stochastic process.
    As explained in a talk by one of the present authors (MK),
    this random field plays an important role for the system.
    In this presentation, we take average of this random field
    to define a deterministic field and determine the
    partial differential equation (PDE) which this field satisfies.
    We call this field the potential field,
    since its derivatives give
    the time-dependent density functions of the eigenvalue process
    and the eigenvector-overlap process.
    The present consideration will provide a mathematical interpretation
    of the calculus reported in physics literature
    (e.g., Burda et al. (2015)).
    The exact solutions of the PDE
    and explicit expressions for the density functions
    are shown for several initial conditions.
    Comparison with numerical simulations will be
    also reported.

    The non-Hermitian matrix-valued Brownian motion
    is the stochastic process of a random matrix
    whose entries are given by independent complex Brownian motions.
    The bi-orthogonality relation is imposed between
    the right and the left eigenvector processes, which allows for
    their scale transformations with an invariant eigenvalue process.
    The eigenvector-overlap process is a matrix-valued process,
    each element of which is given by
    a product of an overlap of right eigenvectors
    and that of left eigenvectors.
    We derive a set of stochastic differential equations
    for the coupled system of the eigenvalue process and the
    eigenvector-overlap process and prove
    the scale-transformation invariance of the system.
    The Fuglede--Kadison (FK) determinant associated with the present
    matrix-valued process is regularized by introducing
    an auxiliary complex variable. This variable is necessary
    to give the stochastic partial differential equations (SPDEs)
    for the time-dependent random field associated with
    the regularized FK determinant and for its logarithmic variation.
    Time-dependent point process of eigenvalues
    and its variation weighted by the diagonal elements of
    the eigenvector-overlap process are
    related to the derivatives of the
    logarithmic random-field of the regularized FK determinant.
    From the SPDEs, a system of PDEs
    for the density functions of these two types of
    time-dependent point processes are obtained.

    Syota Esaki (Fukuoka) and Satoshi Yabuoku (Kitakyushu).

    I will report the recent progress
    of the elliptic extensions in the study of statistical and
    stochastic models in
    equilibrium and nonequilibrium statistical mechanics and
    probability theory $[1]$.
    Using the $R_n$ theta functions $\{\psi^{R_n}_j\}_{j=1}^n$, $n \in \mathbb{N}$
    introduced by Rosengren and Schlosser (2006)
    in association with the seven irreducible reduced affine
    root systems,
    $R_n=A_{n-1}$, $B_n$, $B^{\vee}_n$,
    $C_n$, $C^{\vee}_n$, $BC_n$, $D_n$,
    and their extensions denoted by $\{\Psi^{R_n}_j\}_{j=1}^n, n \in \mathbb{N}$,
    we discuss two groups of
    interacting particle systems, in which $n$ indicates
    the total number of particles in each system
    and $R$ specifies one of the seven types for each model.
    The first group of systems describes
    the noncolliding Brownian bridges
    on a one-dimensional torus $\mathbb{T}$ (\textit{i.e.}, a circle) or an interval,
    and the second one the determinantal point processes
    (DPPs) on a two-dimensional torus $\mathbb{T}^2$.
    The former systems are $(1+1)$-dimensional stochastic processes
    and the latter ones are statistical models of
    stationary point configurations in two dimensions,
    both of which provide mathematical models for
    systems of fermions,
    which are interacting with repulsive forces.
    The boundary conditions
    and the initial/final configurations
    of the noncolliding Brownian bridges,
    and the periodicity conditions of the DPPs are systematically
    changed depending on the choice of $R$ from the seven types.
    We argue the scaling limits
    associated with $n \to \infty$ and precisely define
    the infinite particle systems.
    The connections
    to other statistical systems
    such as the one-component plasma models
    and the Gaussian free fields will be also discussed. \\

    It is well known that the Hermitian matrix-valued Brownian motion (BM),
    H(t), is decoupled into the unitary matrix-valued process
    diagonarlizing H(t) and obtained eigenvalue process.
    The latter process is identified with the Dyson BM with a special
    value of parameter and is realized as the non-colliding BM
    in one dimension.
    It is regarded as the dynamical extension of GUE
    studied in random matrix theory (RMT).
    In the present talk, we discuss the non-Hermitian matrix-valued BM,
    M(t), whose eigenvalues move on the complex plane
    and exhibit a dynamics of the Ginibre ensemble studied in RMT.
    We impose the bi-orthonormality condition between the left- and
    the right-eigenvectors at each time. This means that the
    matrix-valued process diagonalizing M(t) is non-unitary.
    First I will show movies of computer simulations provided by
    my students, Yuya Tanaka, Saori Morimoto, and Ayana Ezoe,
    in order to demonstrate the coupling phenomena
    of the eigenvalue process and the non-unitary matrix-valued
    process for a variety of initial conditions.
    Then I will briefly review the recent results on the SDE
    representation of the processes obtained by Esaki and Yabuoku.
    In contrast with the Dyson BM having the repulsive
    interaction between any pair of particles,
    the eigenvalue process of M(t) is martingale.
    The cross-variations of the eigenvalues define a
    matrix-valued process. It exhibits a time-evolution of
    the overlap matrix whose statistics was
    first studied by Chalker and Mehlig
    for the Ginibre ensemble in RMT.
    We introduce the time-dependent point processes
    of eigenvalues weighted by the values of overlap-matrix elements,
    in addition to the usual eigenvalue point-process.
    Following the electrostatic analogy reported by
    Burda et al. (2015) in physics literature,
    possible hydrodynamic descriptions of these processes
    on the complex plane are shown.

    Schramm--Loewner evolution (SLE) is a stochastic extension
    of the classical Loewner theory in complex analysis
    on a simply connected proper domain of ${\mathbb{C } }$
    such that the driving function of the Loewner chain of
    conformal maps is given by a one-dimensional stochastic process.
    Here we assume that the domain is the upper-half
    complex-plane ${\mathbb{H } }$ and the driving process runs
    on ${\mathbb{R } }$.
    It was proved that the SLE driven by a time changed Brownian
    motion on ${\mathbb{R } }$, $(B_{\kappa t})_{t \geq 0}$, $\kappa >0$,
    determines a one-parameter family of probability laws
    of a random continuous curve in $\overline{\mathbb{H } }$
    connecting 0 and $\infty$,
    and that this family, denoted by
    SLE$_{\kappa}$, $\kappa >0$, covers all probability laws of such
    curves having the conformal invariance and
    the domain Markov property.
    In probability theory and statistical physics,
    the SLE$_{\kappa}$ has been playing a central role in studying
    critical phenomena associated with continuous phase transitions
    and fractal geometries in two dimensions.
    Therefore, it is natural to generalize the SLE theory to describe
    random multiple curves in ${\mathbb{H } }$ driven by
    an interacting particle system on ${\mathbb{R } }$.
    The problem is that the requirement of the conformal invariance
    and the domain Markov property is not sufficient to determine
    a `canonical' family of multiple SLEs.
    Motivated by the recent work by Sheffield on the
    quantum gravity zipper
    and a series of papers by Miller and Sheffield
    on the imaginary geometry,
    we employ the coupling of Gaussian free fields (GFFs)
    and multiple SLEs.
    We show that
    a multiple SLE is correctly coupled with a certain GFF
    if and only if the driving particle system is
    given by Dyson's Brownian motion model studied
    in random matrix theory.
    Dyson's Brownian motion model is also a one-parameter
    ($\beta>0$) family of one-dimensional log-gases.
    The coupling is achieved if and only if $\beta=8/\kappa$.
    The present study on the GFF/multiple SLE coupling enables
    us to clarify the basic properties of the constructed multiple SLE
    (e.g., continuity of multiple SLE curves,
    `phase transitions' at $\kappa=4$ and 8). Moreover, we expect that
    a notion of conformal invariance of SLE
    will enrich the study of random matrix theory
    via the present results on the trinity of
    the GFF, the multiple SLE, and Dyson's Brownian motion model.
    The present talk is based on a joint work
    with Shinji Koshida (Aalto University).

    I have studied Dyson's Brownian motion model with
    Hideki Tanemura and others, which
    is a Hermitian matrix-valued Brownian motion.
    The eigenvalue process is determinantal in space and time
    and the hydrodynamic limit is described by
    the complex Burgers equation in the inviscid limit.
    In the present talk, I review the recent work by

    I will explain new aspects of its eigenvalue process on the
    complex plane: It is dynamically coupled with
    the left and right eigenvectors and hence
    essentially different from Dyson's process on
    the real line.
    Nevertheless, the inviscid Burgers equation
    and the determinantal structure appear
    associated with the eigenvector processes.

    The \textit{Ginibre point process} is given by the eigenvalue
    distribution of a non-hermitian complex Gaussian matrix
    in the infinite matrix-size limit.
    This is a \textit{determinantal point process} (DPP) on the complex
    plane $\C$ in the sense that all correlation functions
    are given by determinants specified by an integral
    kernel called the \textit{correlation kernel}.
    As extensions of the Ginibre DPP,
    a one-parameter family of DPPs is defined on
    $\C^d$, in which $d \in \N$ is the parameter
    and the Ginibre DPP is regarded as
    the lowest-dimensional case ($d=1$).
    We call it the \textit{Heisenberg family of DPPs}, and
    we will explain this reason in the first part of the present talk:
    For each $d \in \N$, the correlation kernel is expressed by
    a matrix-element function of the
    \textit{Schr\"{o}dinger representation}
    of the \textit{Heisenberg group}, and is identified with
    the \textit{reproducing kernel}
    of the \textit{Bargmann-Fock space}.
    Then we prove that any DPP in this family has
    \textit{hyperunifomity} as follows:
    We consider a series of bounded domains
    $\Lambda_n \subset \C^d$,
    which are monotonically increasing and
    $\Lambda_n \to \C^d$ as $n \to \infty$.
    They provide a series of `observation windows' to measure
    local density-fluctuation for an infinite point process
    $\Xi$, and then the hyperuniformity is defined by
    \[
    \lim_{n \to \infty} \frac{\var[\Xi(\Lambda_n)]}{\bE[\Xi(\Lambda_n)]}=0.
    \]
    We show that when $\Lambda_n$ are polydisks, the proof is
    readily given by using the \textit{duality relation}
    between DPPs.
    In the case that $\Lambda_n$ are balls, we have derived
    exact formulas of $\var[\Xi(\Lambda_n)]$ using the modified
    Bessel functions, which provide asymptotic expansions
    for $\var[\Xi(\Lambda_n)]$ in $\vol[\Lambda_n] \to \infty$.
    This talk is based on the joint work with
    T. Matsui (Chuo Univ.) and T. Shirai (Kyushu Univ.),
    and with S. Koshida (Aalto Univ.).

    We consider appropriate inner products and construct
    the orthonormal bases for the Hilbert spaces of $R$-theta functions.
    Using them the reproducing kernels are defined
    and the families of determinantal point processes (DPPs)
    with finite numbers of particles are obtained on a complex plane.
    There the correlation kernels are given by the
    reproducing kernels.
    The double periodicity and symmetry of the DPPs are studied.
    Infinite particle limits provide the Ginibre DPP
    well studied in random matrix theory
    as well as new kinds of infinite DPPs.

    defined by the
    i.i.d.~Gaussian Laurent series.
    The covariance kernel of the GAF is given by
    the weighted Szeg\H{o} kernel of ${\mathbb{A } }_q$
    with the weight parameter $r$
    studied by Mccullough and Shen.
    Conditioning the GAF by giving zeros,
    new GAFs are induced such that
    the covariance kernels are also given by
    the weighted Szeg\H{o} kernel of Mccullough and Shen
    but the weight parameter $r$
    is changed depending on the given zeros.
    We prove that the zero set of the GAF provides
    a permanental-determinantal point process (PDPP)
    in which each correlation function is expressed by
    a permanent multiplied by a determinant.
    If we take the limit $q \to 0$,
    a simpler but still non-trivial
    PDPP is obtained on a punctured unit disk
    ${\mathbb{D } }^{\times} := {\mathbb{D } } \setminus \{0\}$.
    In the further limit $r \to 0$
    the present PDPP is reduced to the
    determinantal point process on ${\mathbb{D } }$ studied by
    Peres and Vir\'ag.
    The present talk is based on
    a joint work with Tomoyuki Shirai

    A point process is a statistical ensemble of
    random nonnegative-integer-valued Radon measures
    on a space equipped with a reference measure.
    We consider the case in which for any integer $n$
    an $n$-point correlation function is well defined
    with respect to the $n$-product of reference measure.
    When an $n$-point correlation function is given by
    a determinant of $n \times n$ matrix for every $n$
    and the entries of matrices are
    determined by a kernel of an integral operator,
    the point process is said to be determinantal
    and the kernel is called the correlation kernel.
    Many examples of determinantal point processes (DPPs)
    have been studied in random matrix theory and correlation
    kernels provide reproducing kernels
    which construct reproducing kernel Hilbert spaces.
    Recently we are interested in the DPPs
    in which correlation kernels are expressed using
    Jacobi's theta functions and Weierstrass' elliptic functions.
    In the present talk we will explain that
    these new examples of DPPs can be regarded as
    elliptic extensions of the classical DPPs and their
    $q$-extensions (trigonometric extensions).
    In particular we will report an elliptic extension of the
    beautiful work by Peres and Vir\'ag published in 2005,
    who considered the Gaussian analytic function (GAF)
    on a unit disk ${\mathbb{D } }$ defined as
    an ensemble of random power series with i.i.d.~complex
    Gaussian coefficients.
    There the covariance kernel of GAF is
    given by the reproducing kernel of the Hardy space on
    ${\mathbb{D } }$ called the Szeg\H{o} kernel of ${\mathbb{D } }$.
    They showed that zeros of the GAF form a DPP whose
    correlation kernel is equal to the Bergman kernel
    of ${\mathbb{D } }$.
    This talk is based on the joint work with Tomoyuki Shirai
    (IMI, Kyushu University).

    A determinantal point process (DPP) is an ensemble
    of random nonnegative-integer-valued Radon measures,
    whose correlation functions are all given by determinants
    specified by an integral kernel called the correlation kernel.
    First we show our new scheme of DPPs in which
    a notion of partial isometies between a pair of Hilbert spaces
    plays an important role.
    Many examples of DPPs in one-, two-, and higher-dimensional
    spaces are demonstrated, where several types
    of weak convergence from finite DPPs to
    infinite DPPs are given.
    Dynamical extensions of DPP are realized in one-dimensional
    systems of diffusive particles conditioned
    never to collide with each other.
    They are regarded as one-dimensional stochastic log-gases,
    or the two-dimensional Coulomb gases
    confined in one-dimensional spaces.
    In the second section, we consider such
    interacting particle systems in one dimension.
    We introduce a notion of
    determinantal martingale and prove that,
    if the system has determinantal martingale representation (DMR),
    then it is a determinantal stochastic process (DSP) in the sense that
    all spatio-temporal correlation function are expressed by
    a determinant.
    In the last section, we construct processes of
    Gaussian free fields (GFFs) on simply connected
    proper subdomains of $\C$ coupled with
    interacting particle systems defined
    on boundaries of the domains.
    There we use multiple Schramm--Loewner evolutions (SLEs)
    driven by the interacting particle systems.
    We prove that, if the driving processes
    are time-changes of the log-gases studied in the
    second section, then the obtained GFF with multiple SLEs
    are stationary.
    The stationarity defines an equivalence relation of
    GFFs, which will be regarded as a generalization of
    the imaginary surface studied by Miller and Sheffield.

    A determinantal point process (DPP) is
    an ensemble of random nonnegative-integer-valued
    Radon measures $\Xi$ on
    a space $S$ with measure $\lambda$,
    whose correlation functions are all
    given by determinants specified by an
    integral kernel $K$ called the correlation kernel.
    We consider a pair of Hilbert spaces,
    $H_{\ell}, \ell=1,2$, which are assumed to
    be realized as $L^2$-spaces,
    $L^2(S_{\ell}, \lambda_{\ell})$, $\ell=1,2$,
    and introduce
    a bounded linear operator ${\cal W} : H_1 \to H_2$
    and its adjoint ${\cal W}^{\ast} : H_2 \to H_1$.
    We prove that if both of ${\cal W}$ and ${\cal W}^{\ast}$ are
    partial isometries and both of ${\cal W}^{\ast} {\cal W}$ and
    ${\cal W} {\cal W}^{\ast}$
    are of locally trace class, then we have unique pair
    of DPPs, $(\Xi_{\ell}, K_{\ell}, \lambda_{\ell})$, $\ell=1,2$,
    which satisfy useful duality relations.
    We assume that ${\cal W}$ admits an integral kernel $W$
    on $L^2(S_1, \lambda_1)$,
    and give practical setting of $W$ which makes
    ${\cal W}$ and ${\cal W}^{\ast}$ satisfy the above conditions.
    By showing several examples,
    we demonstrate that the class of DPPs
    obtained by our method is large enough to
    study universal structures of DPPs.

    First I will explain a general framework of determinantal
    point processes (DPPs) based on the notions of
    partial isometries of Hilbert spaces
    and orthonormal functions.
    As examples of DPPs constructed by this framework,
    several kinds of DPPs are discussed in the two-dimensional
    spaces (e.g., a complex plane, a torus, a cylinder, and a sphere)
    as well as in higher-dimensional spaces.
    Universal properties observed in the bulk scaling limit
    are shown. Systems of stochastic differential equations
    having these DPPs as invariant measures are discussed.
    The present talk is based on the paper
    to be published in Commun. Math. Phys.

    A quantum surface (QS) (resp. an imaginary surface (IS)) is
    an equivalence class of pairs of simply commenced domains
    $D \subsetneq {\mathbb{C } }$ and the Gaussian free fields (GFFs) on $D$
    with the free (resp. Dirichlet) boundary condition
    induced by the conformal equivalence for random metric spaces.
    We define a QS with $N+1$ marked boundary points (MBPs)
    and an IS with $N+1$ boundary condition changing points (BCCPs)
    on $\partial D$ with $N \in {\mathbb{Z } }_{\geq 1}$, in which
    the real (resp. imaginary) part of the sum of ${\mathbb{C } }$-valued
    logarithmic (2D Coulomb) potentials arising from the MBPs (resp. BCCPs)
    is added to GFF in $D$.
    We consider the situation such that the boundary points evolve in time
    as a stochastic log-gas on $\partial D$ and
    multiple random slits are generated in $D$ by the
    multiple Schramm--Loewner evolution (SLE) driven by
    that stochastic log-gas.
    Then we cut the domain $D$ along the SLE slits, restrict the GFF
    on the resulting domain, and pull it back to $D$ following
    the reverse flow of the multiple SLE.
    We prove that if the log-gases on $\partial D$ follow
    the stochastic differential equations well-studied
    in random matrix theory ({\it e.g.}, Dyson's Brownian
    motion model, the Bru--Wishart processes),
    and parameters are properly chosen,
    then the coupled systems of GFFs and multiple SLE slits
    provide stationary processes.
    The obtained random systems are used to solve
    interesting geometric problems called
    the conformal welding problem and the flow line problem.
    The present study extends the previous
    results for a QS with two MBPs reported by Sheffield
    and for an IS with two BCCPs by Miller and Sheffield.
    This is a joint work with Shinji Koshida (Chuo University);

    We introduce new families of determinantal point processes (DPPs)
    on a complex plane ${\mathbb{C } }$, which are classified into seven types
    following the irreducible reduced affine root systems,
    $R_N=A_N$, $B_N$, $B^{\vee}_N$, $C_N$, $C^{\vee}_N$, $BC_N$, $D_N$,
    $N \in {\mathbb{N } }$.
    Their multivariate probability densities are totally elliptic functions
    with periods $(L, iW)$, $0 < L, W < \infty$, $i=\sqrt{-1}$.
    The construction is based on the orthogonality relations
    with respect to the double integrals over the fundamental domain,
    $[0, L) \times [0, iW)$, which are proved in this paper
    for the $R_N$-theta functions introduced by Rosengren and Schlosser.
    In the scaling limit $N \to \infty, L \to \infty$
    with constant density
    $\rho=N/(LW)$ and constant $W$, we obtain four types of
    DPPs with an infinite number of
    points on ${\mathbb{C } }$, which have periodicity with period $i W$.
    In the further limit $W \to \infty$ with constant $\rho$,
    they are degenerated into three infinite-dimensional DPPs.
    One of them is uniform on ${\mathbb{C } }$ and equivalent
    with the Ginibre point process
    studied in random matrix theory, while
    other two systems are isotropic viewed from the origin,
    but non-uniform on ${\mathbb{C } }$.
    We show that the elliptic DPP
    of type $A_N$ is identified with the particle section,
    obtained by subtracting the background effect,
    of the two-dimensional exactly solvable model
    for one-component plasma studied by Forrester.
    Other two exactly solvable models of one-component plasma
    are constructed associated with the elliptic DPPs
    of types $C_N$ and $D_N$.
    Relationship to the Gaussian free field (GFF) on a torus
    is discussed for these three exactly solvable plasma models.

    Dyson model is a stochastic particle system in one dimension R, in which repulsive force acts between any pair of particles with strength proportional to the inverse of distance. This multivariate stochastic process is realized as the system of one-dimensional Brownian motions conditioned never to collide with each other. We can show that this many-body system is exactly solvable and of determinantal in the sense that any spatio-temporal correlation function is expressed by determinant and is controlled by a single continuous function called the correlation kernel. In this lecture, we assume the special initial configuration such that all N particles are concentrated on the origin and we discuss the limit theorems in N ⟶ ∞. Wigner's semicircle law, which is extensively studied in random matrix theory and free probability, is demonstrated as the law of large numbers (LLN), which describes the density profile of particles in R at each time. Two kinds of limits called the bulk scaling limit and the soft-edge scaling limit are introduced in order to obtain determinantal processes with an infinite number of particles. As the central limit theorem (CLT) associated with the latter scaling limit, the Tracy--Widom distribution is discussed.

    Recently, various types of collective behavior observed in swarming micro-organisms, marching insects, flocking birds, and walking pedestrians have been studied in the field of physics. The relation between individual behavior and collective behavior has been investigated from the view point of statistical physics. In our studies, we found that Bacillus subtilis cells as a kind of micro-organisms showed six types of collective behavior depending on the reduced cell length (defined as the ratio of cell length to pool diameter) and the cell density in a circular pool which was made on an agar plate surface. Then, we have confirmed that the interaction of a cell with the brim of a pool, the interaction between cells, and the fluctuation in the moving direction of cells are essential to the collective behavior.

    干渉ブラウン運動のtagged粒子の不変原理に関して、従来より適切かつ精密な定式化を行い、Kipnis-Varadhanの不変原理の対応物が成立することを証明した。
    従来は、Palm測度に対して、無限個の環境粒子系にたいして、tagged粒子のブラウン運動への収束が「測度収束」の意味で成立するという形で、主張が定式化されてきた。これは、80年代前半に行われたGuo-Papanicolauの研究以来の伝統的な定式化ではあるが、tagged粒子から見た他の無限個の粒子家の挙動を記述する確率微分方程式に対する解析となるため、すぐには元来の問題との関係が分かりにくい。
    それに対して、今回は、粒子のラベルを考慮し構造に入れることにより、元々の平行移動不変な平衡分布に関して、可逆な確率力学を記述する確率微分方程式を考え、その個々の粒子が、ブラウン運動に初期条件に関して測度収束するという、より自然なわかりやすい定式化となった。
    また、応用として、1次元の無限粒子系が互いに衝突しない（順序を入れ替えない）という性質をもつとき、極限が常に退化するという結果を得た。この事実自体は、当然の結果だが、ポイントはこれが常に成立するということを、幾何的な結果から平易に示したという一般性を備えている点である。
    ランダム行列に関係する干渉ブラウン運動は、対数関数（2次元クーロンポテンシャル）で相互作用する確率力学である。また、干渉ブラウン運動を含む広い範囲の無限次元確率微分方程式に対して一般論を構築し、更に発展させている最中だが、これに関する最近の研究結果をまとめてreview論文として報告した。

    Highly efficient and high power Si-LEDs were fabricated by dressed-photon-phonon (DPP)-assisted annealing. It was found that Boron atoms, a DPP-creation source, formed a pair, and the separation between the two atoms in the pair was three-times the lattice constant of the Si crystal. The atom pair aligned along the plane normal to the direction of the incident light beam used for the annealing. It was also normal to the polarization direction of this light. Simultaneously with these experimental works, novel mathematical scientific model was developed to analyze the light-matter interaction in a mesoscopic space. The results of the analyses agreed well with the experimental results. Furthermore, statistical model of energy transfer in a random medium via dressed photons was developed.

    We establish a general theory for solving infinite-dimensional stochastic differential equations (ISDE) with symmetry typically appearing in statistical mechanics. In particular, we prove the pathwise uniqueness and the existence of the strong solution under a very general framework. This method is novel, and regards the tail sigma field of the configuration space as a boundary of the ISDE. Furthermore, if the tail sigma field is trivial, then a strong solution exists. If the set of probability-one events is unique, then the pathwise uniqueness of solution holds.
    The method is effective for the ISDE with logarithmic interaction potentials, which appear in random matrix theory.

We clarified the relation between the uniqueness of solutions and the triviality of tail sigma fields. Applying the result, we obtained the uniqueness of strong solutions of ISDEs describing the systems of Brownian motions with long range interaction including logarithmic potential, and determined the Dirichlet forms associated with the systems.

    Correlation functions of the eigenvalues of certain random matrices can be expressed by using determinant. A point configuration whose correlation functions are determinants has repulsive property and is called a determinantal point process. Many mathematical objects can be described as a determinantal point process and analyzed precisely. We study the Ginibre point process, which is a typical model of determinantal point process, and we use this determinantal point process instead of poisson point process as a model of base stations of a cellular network and analyze it. We investigated determinantal point processes from both theoretical and applied mathematical points of view.

We have applied them to the representative random point fields arising from Random Matrix Theory such as Ginibre, Dyson, Bessel random point fields, and have detected and solve the infinite-dimensional stochastic differential equations describing the associated stochastic dynamics. We prove the Palm measures of Ginibre random point field have very strange property that is very different from usual Gibbs measures with Ruelle' s class interaction potentials. We have constructed the time evolutional model of 2D Young diagram and have proved its scaling limit.

    A stochastic process is called determinantal if its correlation functions are represented by determinants. During the research we proved that for any fixed configuration the noncolliding Brownian motion and the noncolliding squared Bessel process are determinantal. When number of particle is infinite, we gave sufficient conditions so that the noncolliding processes are exist and have continuous paths. We also showed the relaxation phenomena for the processes.

We have established morphological diagrams on how colony patterns of bacterial species Escherichia coli and Pseudomonas aeruginosa change when environmental conditions vary. We have also studied the spatiotemporal change of cell density when periodic colony growth occurs. 2. We have investigated scaling properties, especially self-affinity, of growing interface of random patterns, by taking bacterial colonies and real landscapes as examples. 3. We have laid the foundation that the fundamental statistical aspects seen in complex systems in general are described by lognormal distributions, based on our observations of prefectural and municipal populations, our body height and weight, and so on.

    It is known that the distribution of particle positions in Dyson's model of Brownian motions coincides with that of eigenvalues of a Hermitian matrix-valued process, whose entries are independent Brownian motions. We considered a system of noncolliding Brownian motions, in which the noncolliding condition is imposed in a finite time interval (0,T]. This is a temporally inhomogeneous diffusion process and in the limit T to infinity, it converges to Dyson's model. We constructed such a Hermitian matrix-valued process that its eigenvalues are identically distributed with the particle positions of our system of noncolliding Brownian motions.
    As an extension of the theory of Dyson's models for the standard Gaussian random-matrix ensembles, we made a systematic study of hermitian matrix-valued processes. In addition to the noncolliding Brownian motions, we introduced noncolliding systems of generalized meanders and showed that all of the ten classes of eigenvalue statistics in the Altland-Zirnbauer classification are realized as particle distributions in the special cases of these diffusion particle systems.
    Then we proved that these non-colliding diffusions are Pfaffian processes, in the sense that any multitime correlation function is given by a Pfaffian. In the infinite particle limit, we showed that the elements of matrix kernels of the obtained infinite Pfaffian processes are generally expressed by the Riemann-Liouville differintegrals of functions comprising the Bessel functions.

    1. We found a new proof of the fact that there are only two extremal Gibbs states for the two dimensional Ising model based on the percolation argument. As an application of this new method, we proved that there are only two extremal points of translationally invariant Gibbs states for the two dimensional Widom-Rowlinson model for sufficiently low temperatures.
    2. We gave an estimate of the speed of convergence for the time constant of the first passage Ising percolation for temperatures above the critical point.
    3. We proved a Dobrushin-Hryniv type limit theorem for the two-dimensional Widom-Rowlinson model. The conditions for the result to hold are a little relaxed.

    Bacteria form characteristic and diverse colonies according to variation of environmental conditions such as nutrient concentration and substrate hardness. This implies that bacteria live actively by interacting collectively or multicellularly with their environment, instead of living unicellularly and passively. In order to elucidate this kind of collective behavior of biological organisms we have studied the growth mechanism and morphological change in colony formation of bacteria both microscopically and macroscopically. We have established morphological diagrams when varying both nutrient concentration and substrate softness. We have also elucidated the growth conditions and characteristics of various colony patterns for species Bacillus subtilis and Proteus mirabilis. Theoretically we have thoroughly investigated how well we can describe our experimental observations from the reaction-diffusion approach. All these results contribute not only to the study of colony formation of bacteria but also to the enlargement of experimental and theoretical studies on pattern formation of the population of biological organisms in general. The species Proteus mirabilis forms macroscopically almost perfect concentric-ring like colonies with approximately equal spacing by repeating collective migration and rest alternately. We have elucidated phenomenological mechanism for the repeated interface growth of the concentric-ring like colonies.

    1.森林総研の田中浩氏から提供していただいた小川森林保護区の航空写真による実測データに対して,我々が開発したイジングモデルによる解析方法を適用した.その際,パラメータを決定する新しい方法として,熱平衡状態で成立する相関等式を用いる方法を考案した.実際にこの方法を小川森林保護区の実測データの解析に応用すると,これまでのモンテカルロ法による方法ではパラメータを決定できなかった1991年のデータに対しても,パラメータを決定することが出来た.
    2.小川森林保護区の実測データでは,林冠ギャップの有無という2値のデータだけではなく,各サイトでの樹林の最高値が与えられている.このため,林冠ギャップと林冠とを分けるしきい値を変えた場合に,林冠ギャップ・クラスターの統計性がどのように変わるかを調べることも可能である.従来のモンテカルロ法によるパラメータ探索では,しきい値を変えるごとにモンテカルロ・シミュレーションを行わなければならなかったため,系統的なデータ解析は困難であった.しかし今回,熱平衡相関等式を用いる方法が出来たので,しきい値を変えて系統的に調べることが出来た.結果として,しきい値の選び方に依らず,決定されたパラメータはどれもイジングモデルの臨界値に近いものであった.
    3.森林動態に対する別の数理モデルとして,ある種の森林火災のパーコレーションモデルを提案し,計算機シミュレーションを行なった.そして,森林モデルで臨界性が実現される極限として知られているDrossel-Schwabl極限について考察した.

    (2)クラスター間にランダムな競合があるようなdirected percolationを、計算機シミュレーションによって調べた。このような系は、臨界点においてself-affine性をもち、結晶成長系に対して提唱されていたMatsushita-Meakinのスケーリングが成立することが明かとなった。(磯上、松下両氏との共同研究。)

    (4)非平衡臨界現象が見られるとき、その臨界値や臨界指数は、モデルの時間発展を与えるtransition matrixの固有値の、システムサイズL→∞での漸近形によって定められると考えられる。我々は、coalescing dualという関係にある2つのプロセスは、(各々のパラメーターの間にある関係が成り立つと)transition matrix自体は全く異なっていても、その固有値は任意のLにおいて総て等しくなることを証明した。このことは、coalescing dualの関係にあるプロセスは同じuniversality classに属することを示唆する。(乾、宇沢両氏との共同研究)。

    The computational physics becomes most important field in modern physics because the computational power has been increasing exponentially and computational study is most effective analyzing method for many important problems. It has been shown that the special purpose computer systems are useful for the theoretical researches. But such systems have not been available unless the researcher constructs one for his study. The main purpose of this research project is to supply such systems to the researchers who need strong simulation power for their studies for the Ising models.
    The special purpose computer system, named m-TIS2, has been developed in this research project. This machine is dedicated for the Monte Carlo simulation of the Ising models and it is the successor to our previous machine, m-TIS, which was developed in 1988. We have constructed thirteen m-TIS2 and have distributed them to the domestic collaborators. Therefore we have achieved the purpose of this project.
    The m-TIS2 has unique architecture. It uses the XILINX's LCA devices. And its hardware configuration can be modified easily by changing the configuration files written into the m-TIS2 at the beginning of the simulation. The fixed circuit is designed so that the m-TIS2 can hold maximum flexibility. Several configuration files are prepared for several models. For example, the CUBIC can simulate the two-dimensional models including up to the third neighbor interactions and three-dimensional models. The SG can treat <plus-minus>J spin-glass models. It is possible to make dedicated machine for different problems if some appropriate configuration files are prepare
    Our m-TIS and m-TIS2 are the first trial for the special purpose computer systems for theoretical sciences in Japan. And our project has been stimulating many other researches in these fields and several similar domestic projects have followed our project.

  • Theoretical Research of Exotic Phase Transitions

    The research project "Theoretical Research of Exotic Phase Transitions" was performed by the support of the Grant-in-Aid from the Ministry of Education, Science and Culture during two fiscal years from april 1988.
    A general theory of phase transitions, so-called the coherent-anomaly method (CAM) and the super-effective-field theory have been developed to study exotic phase transitions such as spin glasses and chiral orders. It has been shown that there exists no phase transition in the two-dimensional <plus-minus>J Ising spin glass model, but that there exists a phase transition in three dimensions for the same model. The critical point T_<**> and the nonlinear susceptibility exponent gamma_* have been estimated as T_<**> <similar or equal> 1.4J/k_B and gamma_* <similar or equal> 3. Concerning the scalar chital order, it has been found, using the super-effective-field theory, to be quite difficult to occur in the two-dimensional antiferromagnetic Heisenberg model with cross bonds on a square lattice. This result agrees with other numerical studies.
    Suzuki has discovered a new scheme of "fractal path integrals". This is based on the following general decomposition theorem (Suzuki): e^<x(A+B)> = e^<t1A>e^<t2B>e^<t3A>e^<t4B>...e^<tNA> + O(x^<m+1>), for any positive integer m, where {t_j} are all real numbers proportional to x and they are fractal in their distribution. This new scheme including negative time or temperature is also conceptually interesting and it will be applicable to field theory and nuclear physics. In particular, this mew scheme of fractal decomposition of exponential operators is useful in quantum Monte Carlo simulations, if we combine this new approximant with the Trotter formula, because the resultant error becomes of the order of x^<m+1>n^<-m> for the Trotter number n.
    In order to make effective use of the CAM theory, Suzuki has devised the multi-effective- field theory and the confluent-transfer matrix method. The combination of the CAM theory with the former has given the estimate gamma <similar or equal> 1.7498 for the two-dimensional Ising m
