Résumé

In this paper, we consider problems of discrete approximation of special integral operators with the Calderon–Zygmund kernel. We introduce discrete spaces and discrete operators acting in these spaces that are used proposed for for the approximate solution of the corresponding equations. We propose theorems on the solvability of equations with discrete operators, compare integral operators with their discrete analogs, and obtain estimates of errors of approximate solutions.

Détail

Keywords: Calderon–Zygmund kernel, discrete operator, approximation measure, approximate solution.
