带弱奇异项的二阶微分方程正周期解的存在性

Existence of positive periodic solutions of second-order differential equations with weak singularity

摘要:

本文运用Schauder不动点定理获得了一类二阶非线性微分方程正周期解的存在性, 主要结果推广了一些已有结果.

Abstract:

The existence of positive periodic solutions of a class of second-order differential equation is obtained by using the Schauder's fixed point theorem. The main results generalize some recent results.
