摘要: 利用锥不动点定理得到了一类三阶微分方程的奇异非线性边值问题: -(p1(x)(p2(x)y′)′)′=f(x,y), y(0)=y′(0)=y(1)=0正解的存在性, 其中pi(x)∈Ci(0,1)存在有 限多个零点的非负函数.

关键词: 奇异非线性边值问题, 正解, 存在性

Abstract: In this paper we utilize the fixed point theorem in con e to prove the existence of positive solutions to the singular nonlinear boundar y value problems for a class of third order differential equation: -(p1(x)(p2(x)y′)′)′=f(x,y), y(0)=y′(0)=y(1)=0.

Key words: singular nonlinear boundary value problem, positive solution, existenc e
