泛函微分方程的Mawhin定理

Mawhin's Theorem for Nonlinear Functional Differential Equations

利用Liapunov-Schm idt方法和拓扑度理论,将Mawhin关于常微分方程周期解的存在性结果推广到具有超前和滞后的泛函微分方程上.

Using Liapunov-Schmidt method and topological degree theory, we proved some results for the existence of periodic solutions of nonlinear functional differential equations.
