摘要
研究具有时滞和Modified Leslie-Gower HollingⅡ功能性反应的两种群捕食-食饵系统.利用叠合度定理得到此系统周期解存在的充分条件.
In this paper, by using coincidence degree theorem, we study the predator-prey model with delay and modified Leslie-Gower Holling-typeII schemes Sufficient conditions are obtained, which guarantees the existence of positive periodic solution for the model.
