一类奇异四点边值问题的正解

Positive Solutions for a Class of Singular Four-Point Boundary Value Problem

主要研究一类二阶次线性奇异四点边值问题的正解的存在性问题,通过利用上下解方法得出至少存在一个正解的结论。

In this paper, we mainly study the existence of positive solutions for a class of second order sub-linear four-point singular boundary value problem. By using the method of upper-lower solutions, the existence of positive solutions for a class of sub-linear boundary problems is obtained.
