一类四阶奇异微分方程解的存在性

Existence of Positive Solution to Fourth-Order Singular Differential Equations

利用Schauder不动点定理及上下解方法讨论了一类非线性四阶微分方程奇异边值问题正解的存在性.推广和改进了已有的结果.

This paper studies the existence of positive solution for fourth order singular boundary value problems. The proof uses Schauder fixed point theorem and upper and lower solutions method. It shall extend and improve some results.
