Title: Positive solutions for systems of third-order
       generalized Sturm-Liouville  boundary-value problems with
       (p,q)-Laplacian

Abstract:
 In this work, we use the Leggett-Williams fixed point theorem
 to prove the existence of at least three positive solutions to
 a system of third-order ordinary differential equations
 with (p,q)-Laplacian
