摘要
构造一类成年食饵具有扩散的比率依赖型时滞捕食系统,利用Gaines-Mawhin’s重合度原理,推导了该系统周期解的存在性.
A class of ratio-dependent predator-prey system with time delays and the adult prey diffusion is constructed. By using the Gaines-Mawhin＇s, continuation theorem of coincidence degree theory, the existence of periodic solution of the system is investigated.
