摘要
利用重合度理论和一些分析技巧,研究一类具有脉冲和时滞的合作系统,得到该系统存在正周期解的结果.结果表明,具有脉冲和时滞的合作系统,在满足一定的充分条件,该系统至少存在一个正周期解.
In this paper,by means of some analysis techniques and the continuation theorem of coincidence degree theory,we study a class of mutualism systems with impulses and delays.The existence of positive periodic solutions for the systems is proved.The result expresses that,under some sufficient conditions,there exists at least a positive periodic solution for the system.
