具有饱和传染力的Schoner竞争差分系统的概周期解

Almost Periodic Solution for a Schoner Competitive Difference System with Saturated Infectious Force

研究了一类具有饱和传染力的Schoner竞争差分系统,得到了系统持久生存的充分条件.同时,当系统是概周期系统时,通过构造适当的Lyapunov函数,得到了保证系统存在唯一全局吸引的概周期解的充分条件.

In this paper, an almost periodic solution of Sehoner competitive difference system with saturated infections force is studied. Some sufficient conditions for the permanence are derived. Meanwhile, by constructing a suitable Lyapunov founction, sufficient conditions are obtained for the existence of a unique global attractivity almost periodic solution when the system is almost periodic.
