Abstract
In this paper we prove the existence and concentration behavior of positive ground state solutions for quasilinear Schrödinger equations of the form −ε 2Δu + Vzu − ε 2 Δu 2u = hu in the whole twodimension space where ε is a small positive parameter and V is a continuous potential uniformly positive The main feature of this paper is that the nonlinear term hu is allowed to enjoy the critical exponential growth with respect to the Trudinger–Moser inequality and also the presence of the second order nonhomogeneous term Δu 2u which prevents us to work in a classical Sobolev space Using a version of the Trudinger–Moser inequality a penalization technique and mountainpass arguments in a nonstandard Orlicz space we establish the existence of solutions that concentrate near a local minimum of V
