非自治Lotka-Volterra互惠扩散系统的概周期解和全局稳定性

Almost Periodic Solution and Stability for Nonautonmous Cooperative Lotka-Volterra Diffusion System

本文主要考虑在两个斑块中 ,两个互惠物种的非自治Lotka -Volerra模型 ,并且两个物种中每个物种都能在自己班块内部和外部独立地扩散 ,利用构造的Liapunov函数 。

In this paper,two cooperative Lotka-Volterra populations in the two-patch-system with diffusion are considered.Each of the two spiecies can diffuse indepently and discretely between its in trapatch and interpatch.By means of constructing Liapunov function,under moderate condition,the system has a unique almost periodic solution which is globally and asymptotically stable.
