一类时滞泛函微分方程三个正周期解的存在性

Existence of Triple Positive Periodic Solutions for a Class of Delay Functional Differential Equations

该文利用Leggett-Williams不动点定理讨论了一类时滞泛函微分方程三个正周期解的存在性.

In this paper,we establish the existence of three positive periodic solutions for a class of delay functional differential equations by the Leggett-Williams fixed point theorem.
