In this article, we study the nonlinear equation
where q>p>1. For positive potentials (w>0), we investigate the existence of sign-changing solutions with prescribed number of zeros depending on the increasing initial parameters. For negative potentials, we deduce a finite interval in which the positive solution will tend to infinity. The main methods using in this work are the scaling argument, Prufer-type substitutions, and some integrals involving the p-Laplacian.
