摘要 在时间测度上研究了具有Hassell-varley型功能反应和收获项的捕食系统多周期解的存在性.利用重合度理论中的延拓定理,得到了该系统至少存在4个不同正周期解的充分条件. In this paper , we consider the existence of more periodic solution for a class of predator-prey system on time scales with Hassell-varley functional response andharvesting .By using a continuation the-orem based on cioncidence degress theory ,sufficient conditions of at least four positive periodic solutions are obtained .
