一类基于比率依赖的食物链系统的周期解
Periodic solutions for ratio-dependent food chain system
摘要
Abstract
A delayed model of three species food chain with ratio dependence is investigated. By using the coincidence degree theory and analysis techniques, sufficient conditions for existence of periodic solutions are established.关键词
