SINGULARLY PERTURBED INTEGRAL EQUATION
WITH A RAPIDLY OSCILLATING INHOMOGENEITY

Abstract

In this paper, we consider singularly perturbed integro-differential equations with a rapidly oscillating right-hand side, including an integral operator with a slowly varying kernel. The main goal of this work is to generalize the Lomov's regularization method and to reveal the influence of the rapidly oscillating right-hand side on the asymptotics of the solution to the original problem.
