摘要：

In this paper, we investigate the existence of positive solutions for a class of nonlinear second-order four-point boundary value problems with alternating coefficient. Our approach relies on the Krasnosel'skii fixed point theorem. The result of this paper is new and extent the previously known result. (C) 2008 Elsevier Ltd. All rights reserved.
