摘要
利用MAWHIN重合度理论中的延拓定理研究了具有Holling 型功能性反应的捕食者-食饵系统非平凡周期解的存在性,得到了周期解存在的一个充分条件,并对一些参数和初始值进行了数值模拟.
By using the continuation theorem based on coincidence degree theory,the global existence of positive periodic solution for a periodic predatorprey system with Holling typeⅢ functional response is studied in this paper.A set of easily verifiable sufficient conditions are obtained.Numerical simulations are given to show our theoretical result.
