On the problem of calculation of correlation functions in the six-vertex model with domain wall boundary conditions

, 2011
The problem of calculation of correlation functions in the six-vertex model with domain wall boundary conditions is addressed by considering a particular nonlocal correlation function, called row configuration probability.

On the spectrum of a stationary problem with nonlocal integral type boundary condition

Lietuvos Matematikos Rinkinys, 2004
We investigated a eigenvalue problem for simple second order ordinary differential equation with one inte­gral type nonlocal boundary condition. The eigenvalues and eigenfunctions of such problem are depending on few parameters in the nonlocal boundary ...

The nonlocal boundary problem with perturbations of antiperiodicity conditions for the eliptic equation with constant coefficients

Karpatsʹkì Matematičnì Publìkacìï, 2018
In this article, we investigate a problem with nonlocal boundary conditions which are perturbations of antiperiodical conditions in bounded $m$-dimensional parallelepiped using Fourier method. We describe properties of a transformation operator $R:L_2(G)

Spectral characteristics of a nonlocal problem for two linear systems of partial differential equations

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2017
We study the boundary-value problem for a linear system of differential equations written in the form of differential-operator equations $$ aD_t u(t)+bBu(t)=f(t) $$ with nonlocal boundary conditions at $t$.
