Double positive solutions for a nonlinear four-point boundary value problem with a p-Laplacian operator

In this paper, we study the existence of positive solutions for a nonlinear four-point boundary value problem with a p-Laplacian operator. By using a three functionals fixed point theorem in a cone, the existence of double positive solutions for the nonlinear four-point boundary value problem with a p-Laplacian operator is obtained, which is different from the previous ones.
