摘要 利用Gaines和Mawhin的重合度理论,研究了一类状态依赖时滞的脉冲Logstic系统,获得了该系统至少存在一个正周期解的充分条件. With the help of a continuation theorem based on Gaines and Mawhin's coincidence degree, a state-dependent delay Logistic system with impulse is investigated and a set of sufficient conditions are obtained for the existence of at least one positive periodic solution.
