Abstract

In this paper, the Lomov’s regularization method is generalized to a singularly perturbed integro-differential equation with a fractional derivative and with a rapidly oscillating inhomogeneity. The main goal of the work is to reveal the influence of a rapidly changing kernel on the structure of the asymptotic of the problem solution and to study additional boundary functions that are generated by rapidly oscillating in homogeneities.
