摘要
运用Leray-Schauder不动点定理研究一类脉冲泛函微分方程的正周期解的存在性,获得了存在正周期解的充分条件,改进了已知文献中的结果.
In this paper,we investigate the existence of positive periodic solutions of impulsive functional differential equations by using Leray-Schauder theorem.Some sufficient conditions for the existence of positive periodic solutions are obtained,which improve the results of literature.
