Existence of positive solutions for semipositone multi-point boundary value problems
In this paper, the existence of positive solutions for a semipositone second-order multi-point boundary value problem is investigated. By using Krasnosel'skii's fixed point theorem, sufficient conditions that guarantee the existence of at least one positive solution are obtained. (C) 2011 Elsevier Ltd. All rights reserved.
