Abstract. In this paper, we study the existence of positive periodic solutions to two classes of neutral functional differential equations. By using Schauder’s fixed point theorem and Krasoselskii’s fixed point theorem in cones, we demonstrate that the problems have infinitely many positive periodic solutions under appropriate conditions. Some examples are presented to illustrate our results.
