摘要
使用Leray-Schauder不动点定理研究一类高维脉冲泛函微分方程的正周期解的存在性,获得了该类方程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,by using Leray-Schauder theorem,the authors discuss the existence of positive periodic solutions for a class of higher-dimension impulsive functional differential equations.Some sufficient conditions for the existence of positive periodic solutions are obtained,which improve the results of literature.
