具连续时滞的三种群混合模型的周期正解

Positive Periodic Solution of Three Species Mixed Model with Continuous Time Delay

研究三种群之间既有捕食关系又有竞争关系的混合非自治连续时滞模型 ,通过使用Burton定理和Lya punov函数方法 ,得到了该系统存在唯一。

This paper discusses a nonautonomous continuous delay mixed model with predatoriness and competition of three species. Sufficient conditions are derived that guarantee the existence and global asymptotic stability of the positive periodic solution by applying the Burton theorem and the method of lyapunov function.
