摘要
通过使用比较定理和微分不等式技巧,研究带有相互干扰和时滞的HollingⅢ型食饵-捕食者系统的持久性.在此基础上,我们构造合适的Lyapunov函数,获得该系统全局吸引性的充分条件.
In this paper,by using the comparison theorem and differential inequality skills,we study the permanence of a Holling Ⅲ type predator-prey system with mutual interference and time delays.Based on the permanence result,by constructing a suitable Lyapunov functional,we eastablish sufficient conditions of globally attractive for the considered system.
