In this article, we study the existence of infinitely many nontrivial solutions for a class of superlinear p-Laplacian equations -Delta(p)u + V (x)vertical bar u vertical bar(p-2) u = f (x,u), where the primitive of the nonlinearity f is of subcritical growth near co in u and the weight function V is allowed to be sign-changing. Our results extend the recent results of Zhang and Xu [Q. Y. Zhang, B. Xu, Multiplicity of solutions for a class of semilinear Schrodinger equations with sign-changing potential, J. Math. Anal. Appl 377(2011), 834-840].
