Resolvent Approximations in L2-Norm for Elliptic Operators Acting in a Perforated Space
Современная математика: Фундаментальные направления, 2020 We study homogenization of a second-order elliptic differential operator Aε = - div a(x/ε)∇ acting in an ε-periodically perforated space, where ε is a small parameter. Coefficients of the operator Aε are measurable ε-periodic functions. The simplest case

On One Method of Studying Spectral Properties of Non-selfadjoint Operators
Abstract and Applied Analysis, 2020 In this paper, we explore a certain class of Non-selfadjoint operators acting on a complex separable Hilbert space. We consider a perturbation of a nonselfadjoint operator by an operator that is also nonselfadjoint.

Properties of the resolvent of singular q-Dirac operators
Electronic Journal of Differential Equations, 2020 In this article, we investigate the resolvent operator of a singular q-Dirac system. We obtain an integral representations for the resolvent of this system, in terms of the spectral function.
