In this paper, by using Krasnoselskii's fixed point theorem in a cone, we study the existence of single and multiple positive solutions to the three-point boundary value problem (BVP) y" (t) + a (t)f (y(t)) = 0, 0 < t < 1, y'(0) = 0, y(1) = betay(eta), where 0 < eta < 1, 0 < beta < 1. As an application, we also give some examples to demonstrate our results. (C) 2002 Published by Elsevier Science Inc.
