一类无穷时滞泛函微分方程的周期解
Periodic Solutions of a Class of Functional Differential Equations with Infinite Delay
【摘要】 通过构造算子讨论了一类无穷时滞泛函微分方程的周期解问题,利用Schauder不动点定理在新的条件下得到了其周期解的存在性及唯一性.推广和改进了已有文献中的相关结果.
【Abstract】 By means of the Schauder fixed point theorem,this paper investigates the existence of periodic solutions for a class of functional differential equations with infinite delay.A set of sufficient conditions to guarantee the existence of periodic solutions of the systems is obtained which extends and improves the related known works in the literature.
