Multiple positive solutions for a second-order three-point boundary value problem

In this paper, we study the second-order three-point boundary value problemu^''(t)+a(t)u^'(t)+b(t)u(t)+h(t)f(u)=0,[email protected]?(0,1),u(0)=0,@au(@h)=u(1).The existence criteria for multiple positive solutions is obtained by using Krasnoselskii fixed point theorem and Leggett-Williams fixed-point theorem.
