一类离散的Lotka-Volterra竞争系统的概周期解

Almost Periodic Solutions of a Discrete Lotka-Volterra Competition System

利用极限和微分以及不等式放缩的方法,讨论了一类Lotka-Volterra竞争系统的解的有界性,得到了其存在唯一且全局吸引的概周期解的充分条件,推广了Zhong Li的结论.

By using the method of limit,differential and the grading of inequalities,the boundedness of solutions of a class of Lotka-Volterra competition system was discussed.Sufficient conditions were obtained for the existence of a unique almost periodic solution which is globally attractive.The conclusions of Zhong Li were generalized.
