Abstract

Abstract: The present paper deals with the periodic solutions for a class of functional differential equations. Sufficient conditions that guaranteed the existence of periodic solutions for this problem were obtained by the method of pairing exact differential equation. The expressions of periodic solutions were obtained by the fractionalstep method. Furthermore, some examples were presented to illustrate the main result in this paper.

Key words: periodic solution, exact differential equation, fractional step method
