Abstract: In this paper, we consider a singularly perturbed integro-differential equation with a rapidly oscillating right-hand side, which includes an integral operator with a rapidly 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 and a rapidly varying kernel on the asymptotics of the solution to the original problem.

Keywords: singular perturbation, integro-differential equation, rapidly oscillating right-hand side, rapidly varying kernel, regularization, solvability of iterative problems.
