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 $t$.

Structure and asymptotic expansion of eigenvalues of an integral-type nonlocal problem
Electronic Journal of Differential Equations, 2016 We study the structure of eigenvalues of second-order differential equations with nonlocal integral boundary conditions. Moreover, we consider the asymptotic expansion of the eigenvalues and the corresponding eigenfunctions, which shows that the ...

Riesz basis of Coifman and Meyer's local sine and cosine type
Journal of Mathematical Analysis and Applications, 2003 The author finds a Riesz basis for \(L^2(\mathbb{R})\) of the form \(\{b_{I_k}(x) \sin \lambda_k x\}\), with \(b_{I_k}(x)\) Bell functions, by perturbing the local sine and cosine orthonormal bases of Coifman and Meyer.

On one non-local problem for axisymmetric Helmholtz equation
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011 Non-local boundary problem for the axisymmetric Helmholtz equation is explored. The uniqueness of the solution is proved by the spectral method. The conditions of solvability are found.
