Abstract

Abstract: In this paper, we consider the three-point boundary value problem \phi_p（u′′（t）））′+a（t）f（t, u（t）, u′（t）, u′′（t）） = 0, t ∈ [0, 1] subject to the boundary conditions u（0） =βu′（0）, u′（1） = αu′（η）, u′′（0） = 0, where \phi_p（s） = |s|^p-2s with p > 1, 0 < α, η < 1and 0 ≤β < 1. Applying a fixed point theorem due to Avery and Peterson, we study the existence of at least three positive solutions to the above boundary value problem.

Key words: third-order three-point boundary value problem, positive solution, fixed point theorem
