摘要
研究一类非自治的含分布时滞和扩散Lotka-Volterra竞争模型的渐近性质.通过建立适当的Lyapunov函数,对模型进行定性分析,获得其正解一致持久和全局渐近稳定的充分条件.
In this paper, the asymptotic behavior for a non-autonomous Lotka-Volterra competitive model with time delay and diffusion is studied. It is proved that the system is uniformly persistent under appropriate conditions, and some simple sufficient conditions are given for global asymptotic stability of positive solution by constructing appropriate Lyapunov function.
