The Eigenspace Spectral Regularization Method for Solving Discrete Ill-Posed Systems
Journal of Applied Mathematics, 2021 This paper shows that discrete linear equations with Hilbert matrix operator, circulant matrix operator, conference matrix operator, banded matrix operator, TST matrix operator, and sparse matrix operator are ill-posed in the sense of Hadamard.

Simplification method for nonlinear equations of monotone type in Banach space
Журнал Средневолжского математического общества, 2021 In a Banach space, we study an operator equation with a monotone operator $T.$ The operator is an operator from a Banach space to its conjugate, and $T=AC,$ where $A$ and $C$ are operators of some classes.

THE H-POLARIZED ELECTROMAGNETIC WAVE DIFFRACTION BY MULTI-ELEMENT PLANE SEMI-INFINITE GRATING
Radio Physics and Radio Astronomy, 2014 The H-polarized wave diffraction by multi-element plane semiinfinite periodic strip grating is considered. The problem is reduced to a nonlinear operator equation with respect to the unknown reflection operator of a structure. The equation is obtained as
