一类泛函微分方程的多重正周期解(英文)
Multiple Positive Periodic Solutions of a Class of Functional Differential Equations
【摘要】 联合运用Krasnoselskii不动点定理和Avery-Henderson不动点定理研究一类泛函微分方程的多重正周期解的存在性,获得了存在多重正周期解的充分条件.
【Abstract】 In this paper,by combining the Krasnoselskii fixed point theorem with the Avery-Henderson fixed point theorem,we investigate the existence of multiple positive periodic solutions of a class of functional differential equations.Some sufficient conditions for the existence of multiple positive periodic solutions are obtained.
