二阶非线性常微分方程组耦合系统的奇异边值问题正解的存在性

Positive solutions for singular boundary value problems of a coupled system of nonlinear ordinary differential equations

本文利用不动点指数理论讨论了二阶非线性常微分方程组耦合系统的奇异边值问题多个正解的存在性,得到了两个正解的结果.

By using fixed point theorem of cone expansion and compre, ssion, this paper discusses the existence of multiple positive solutions for sinsular boundary value problems of a coupled system of nonlinear ordinary differential equations. Two positive solutions are abtained.
