Abstract

ABSTRACT In this paper we study the existence and approximation of the solutions for some systems of nonlinear integro-differential equations with having retarded arguments and boundary conditions. The numerical–analytic method has been used to study the periodic solutions of ordinary differential equations which were introduced by A. M. Samoilenko.
