In this paper, we study the quasilinear Schrodinger equation -epsilon(2)Delta u + V(x)u - epsilon(2)u Delta(u(2)) = Q(x)u(3), u is an element of H-1(R-3), where epsilon > 0 is a parameter, V and Q are positive bounded functions. For the equation with three times growth, we establish the existence of ground states for epsilon small using the method of Nehari manifold. We also describe the concentration phenomena of ground states as epsilon -> 0. (C) 2017 Elsevier Inc. All rights reserved.
