Abstract

This article discusses a class of singularly perturbed system of equations with discontinuous right-hand side when the small parameters before the highest-order derivative are the same. Sufficient conditions for existence of a smooth solution with internal layer of the problem are introduced and its asymptotic expansion is constructed.
