Existence of positive solutions for a class of $$\left( p\left( x\right) , q\left( x\right) \right) $$px,qx-Laplacian systems

Using sub-super solutions method, we study the existence of weak positive solutions for a new class of the system of differential equations with respect to the symmetry conditions. Our results are natural extensions from the previous ones in Fan (J Math Anal Appl 330:665–682 2007), Zhang (Nonlinear Anal 70:305–316 2009).
