摘要

In this paper we study the existence of nontrivial classical solution for the quasilinear Schrodinger equation: -Delta u + V(x)u + k/2 Delta(u(2))u = f (u), in R-N, where N >= 3, f has subcritical growth and V is a nonnegative potential. For this purpose, we use variational methods combined with perturbation arguments, penalization technics of Del Pino and Felmer and Moser iteration. As a main novelty with respect to some previous results, in our work we are able to deal with the case k > 0 and the potential can vanish at infinity.
