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.
