Periodic Solution for a Holling Functional Response Predator-prey System with Sparssing Effect
摘要/Abstract
摘要:
利用重合度理论讨论了稀疏效应下Holling第Ⅱ型功能性反应2种群捕食者食饵周期系统的正周期解,得到了该生物系统一系列容易验证的正周期解存在的充分条件.
Abstract:
By using analysis technique and the method of coincidence degree,the existence of the periodic solution for an nonautonomous predator-prey system with sparssing effect and Holling type Ⅱ funcional response is established.
