摘要
研究了一类具有收获率和Crowley-Martin型功能反应的脉冲捕食系统的正概周期解.通过利用重合度理论延拓定理和不等式分析技巧,获得了该系统至少存在4个正概周期解的充分条件,推广和改进了早期文献的相关结果.
This paper investigates the existence of positive almost periodic solutions for an impulses predator-prey system with Crowley-Martin functional response and harvesting terms.By using a continuation theorem through coincidence degree theory and inequality analysis technique,some sufficient conditions for the existence of at least four positive almost periodic solutions of the system are obtained,which generalize and improve the related results of early literature.
