摘要
对一类具有脉冲生育的Watt型捕食扩散系统,限制捕食者只能在一个斑块中活动,利用重合度理论得到了系统存在正周期解的充分条件。
The existence of periodic solution of a periodic Watt-type predator-prey system where the prey disperses in patchy environment with two patches are investigated . With the continuation theorem of coincidence degree theory, the existence of a positive periodic solution is obtained for such a system.
