【摘要】 研究了具有渐近周期系数的两种群扩散竞争系统,该系统由n个斑块组成,其中一种群可以在n个斑块之间扩散,而另一种群在一个斑块中,不能扩散.结合运用Liapunov函数,得到该系统唯一存在全局渐近稳定的渐近周期解的条件.更多还原

【Abstract】 A asymptotically periodic ecological competitive system with diffusion is stuied. The system,which is consisted of n-pathes,has two competitors,one can diffuse among n-pathes,but the other is confined to one patch and cannot diffuse. By means of constructing a suitable Liapunov function,we obtain the system have a unique asymptotically periodic solution which is globally asymptotically stable.更多还原
