摘要:

考察了一个非线性二阶周期微分系统的正解, 其中非线性项关于时间和空间变量两者均可为奇异的. 通过构造适当的控制函数并且利用锥上的
Guo-Krasnoselskii 不动点定理建立了单个和多重正解的存在性.

关键词: 奇异微分系统, 周期正解, 不动点定理

Abstract:

The positive solutions are considered for a nonlinear second-order periodic differential system in which the nonlinear terms may be singular with respect to both time and space variables. By constructing suitable control functions and applying Guo-Krasnoselskii fixed point theorem on cone, the existence of single and multiple positive solutions is established.

Key words: Singular differential system, Periodic positive solution, Fixed point theorem
