Abstract:

In this paper we consider the existence, multiplicity, and nonexistence of positive periodic solutions for n -dimensional nonautonomous functional differential system , where are -periodic in and there exist -periodic functions such that for all with and , exist for ; are -periodic functions and , for ; is an -periodic function. We show that the system has multiple or no positive -periodic solutions for sufficiently large or small , respectively.
