Abstract

By applying a fixed point theorem due to Avery and Peterson, we study the existence of at least three positive solutions for the one-dimensional p-Laplacian differential equation, (@f"p(u^'(t)))^'+q(t)f(t,u(t),u^'(t))=0,t@?(0,1), subject to the following multipoint boundary condition, u^'(0)=@?i=1n@a"iu^'(@x"i),u(1)=@?i=1n@b"iu(@x"i), where @f"p(s)=|s|^p^-^2s with p1. The interesting point is the nonlinear term f is involved with the first-order derivative explicitly.
