Positive solutions for second-order singular three-point boundary-value problems with sign-changing nonlinearities

Abstract

In this article, we study the existence and uniqueness of the positive solution for a second-order singular three-point boundary-value problem with sign-changing nonlinearities. Our main tool is a fixed-point theorem.
