摘要
利用Krasnosel'skii不动点定理研究了一类二阶非线性常微分方程的三点边值问题正解的存在性问题 ,得到了正确存在的几个充分条件 .
In this paper,the existence of positive solutions for a second-order three-point boundary value problem is investigated.By using Krasnosel'skii fixed point theorem,several sufficient conditions for the existence of positive solutions are obtained.
