    We consider the n² × n² real symmetric and hermitian matrices Mₙ, which are equal to the sum mn of tensor products of the vectors Xμ = B(Yμ ⊗ Yμ), μ = 1, . . . ,mn, where Yμ are i.i.d. random vectors from Rⁿ(Cⁿ) with zero ...
  • Fluctuations of Interlacing Sequences 
    Sodin, S. (Журнал математической физики, анализа, геометрии, 2017)
    In a series of works published in the 1990s, Kerov put forth various applications of the circle of ideas centered at the Markov moment problem to the limiting shape of random continual diagrams arising in representation ...
  • Homogenized Model of Non-Stationary Diffusion in Porous Media with the Drift 
    Goncharenko, M.; Khilkova, L. (Журнал математической физики, анализа, геометрии, 2017)
    We consider an initial boundary-value problem for a parabolic equation describing non-stationary diffusion in porous media with non-linear absorption on the boundary and the transfer of the diffusing substance by fluid. ...

    The purpose of the article is to study an f-cosymplectic manifold M admitting Ricci solitons. Here we consider mainly two classes of Ricci solitons on f-cosymplectic manifolds. One is the class of contact Ricci solitons. ...
