We study the existence of positive solutions of the quasilinear problem
⎧ $-Δ_N u + V(x)|u|^{N-2}u = f(u,|∇u|^{N-2}∇u)$, $x ∈ ℝ^N$,
⎨
⎩ u(x) > 0, $x∈ ℝ^N$,
where $Δ_N u = div(|∇u|^{N-2}∇u)$ is the N-Laplacian operator, $V:ℝ^N → ℝ$ is a continuous potential, $f:ℝ × ℝ^N → ℝ$ is a continuous function. The main result follows from an iterative method based on Mountain Pass techniques.
