摘要
通过使用一般连续定理和微积分不等式技巧,研究带有收获项的时滞Holling-II型食饵-捕食系统的动态特征,获得了带有收获项的时滞Holling-II型食饵-捕食系统存在4个正周期解的充分条件.
In this paper,a delayed predator-prey systems with Holling-II type functional response and Harvesting Terms has been investigated.With the generalized continuation theorem and differential inequality skills,the existence of four positive periodic solutions has been established for delayed predator-prey systems with Holling-II type functional response and Harvesting Terms.
