一类自治中立型泛函微分方程的周期解

Periodic solutions of a class of autonomous neutral type funcitonal differential equation

研究一类自治中立型泛函微分方程的周期解。运用不动点原理结合Kaplan-Yorke技巧的方法,得到其周期解存在的充分条件。

This paper discussed periodic solutions of a class of autonomous neutral type functional differential equation. By using fixedpoint theory and KaplanYorke method, the sufficient condition of its periodic solution was obtained.
