摘要: 该文讨论了一类离散Leslie捕食与被捕食系统,获得了该系统的持久性,当系统为周期系统时,得到了它的周期解的存在性,并且在某些条件下,该周期解是全局稳定的.

关键词: Leslie捕食与被捕食系统, 持久性, 周期解, 全局稳定性

Abstract: The paper discusses a class of discrete Leslie predator-prey system. The authors obtain the persistence of the system, assuming that the coefficients in the system are periodic and the existence of a periodic solution. Under some additional conditions, the periodic solution is globally stable.

Key words: Leslie predator-prey system, Persistence, Periodic solution, Globally stable.
