非自治Lotka-Volterra竞争系统的持久性与正概周期解

Permanence and positive almost periodic solutions of nonautonomous Lotka-Volterra competitive system

利用微分不等式和Liapunov第二方法 ,研究了二维非自治Lotka -Volterra竞争系统的持久性与正概周期解的存在性、唯一性及全局渐近稳定性。

In this paper , for nonautonomous Lotka―Volterra co mpetitive system ,it has been proved that, the permanence and the existence, uni queness and global asymptotic stability of positive almost periodic solutions by using .differential inequality and Liapunov second method.
