Existence of Positive Periodic Solutions of a Predator-prey System with Functional Response

摘要：

In this paper, we establish a nonautonomous predator-prey systems with functional response,and study the existence of positive periodic solutions of the systems by the continuation theorem of the coincidence degree theory. A set of easily verifiable sufficient conditions are obtained for the existence of positive periodic solutions. The main result is verified by numerical simulation.
