摘要: 研究了在两个斑块具有迁移效应和收获率的捕食者--食饵系统,其中的功能性反应函数是具有一般性的Hassell-Varley-Holling功能性反应。 利用迭合度理论连续定理,对系统的解的界可能出现的各种情形进行了细致分析,建立了多个周期解存在的充分条件Abstract: his paper considers a predator prey system with dispersal and harvest, in which the functional response is the general Hassell--Varley--Holling function. Based on continuous theorem of coincidence degree theory, we analyze the bound of solutions of this system, and establish sufficient conditions of the existence of multiple periodic solutions
