摘要
讨论了一类具有反馈控制的非自治3种群捕食系统的持续性和周期解,证明了在适当条件下该系统是持续生存的,得到该系统存在周期解的充分条件,并举例说明了定理的可实现性.
In this paper, the persistence and periodic solution of a kind of nonautonomous three species predator-prey system with feedback control is discussed. It is proved that the system is permanent under some conditions . sufficient conditions are established for existing periodic solution of the system,Furthermore,it is illustrated that the theorem is achieveable according to some examples.
