Using variational methods combined with perturbation arguments, we study the existence of nontrivial classical solution for the quasilinear Schrödinger equation -Δu+ V(x)u+ \fracκ2[Δ|u|2]u=l(u), x∈ℝN, where V:ℝN→ ℝ and l:ℝ → ℝ are continuous function, κ is a parameter and N≥ 3. This model has been proposed in plasma physics and nonlinear optics. As a main novelty with respect to some previous results, we are able to deal with the case κ>0.
