具有Hassell-Varley型功能性反应的捕食者-食饵系统周期解的存在性

Existence of periodic soluton of a predator-prey system with Hassell-Varley functional response

利用重合度理论中的延拓定理,讨论了一类时标动力学方程所刻画的具有Hassell-Varley型功能性反应的捕食者-食饵系统周期解的存在性,得到了该系统存在周期解的充分条件.

With the help of a continuation theorem in coincidence degree theory,some sufficient criteria are established for the existence of positive periodic solution to a periodic predator-prey system with Hassell-Varley type functional response governed by a dynamic equation on general time scales.
