Abstract

Let f:[0,1]times [0,infty)rightarrow [0,infty) be continuousand ain C([0,1],[0,infty)),and let xi_{i}in (0,1) with0<xi_{1} <xi_{2}<cdots<xi_{m-2}<1,a_{i}, b_{i}in [0,infty)with 0<sum_{i=1}^{m-2}a_{i}<1 andsum_{i=1}^{m-2}b_{i}<1.This paper is concerned with thefollowing m-point boundary value problem: x^{''}(t)+a(t)f(t,x(t))=0, tin (0,1),x^{'}(0)=sum_{i=1}^{m-2}b_{i}x^{'}(xi_{i}),x(1)=sum_{i=1}^{m-2}a_{i}x(xi_{i}) . The existence,multiplicity and uniqueness of positive solutions of this problemarediscussed with the help of two fixed point theorems in cones, respectively.
