二阶奇异微分方程边值问题正解的存在性

The Existence of Positive Solutions to Boundary Value Problems of Second Order Singular Differential Equations

该文通过构造一个特殊的锥,利用锥压缩与锥拉伸不动点定理,研究了一类二阶奇异微分方程边值问题两个正解的存在性,改进了最近的一些结果.

In this paper, by constructing a special cone and using the fixed point theorems of cone expansion and cone compression, the existence of two positive solutions to a class of boundary value problem of second order singular differential equations is investigated. The results presented here improve some recent results.
