Abstract: In this paper we study the existence of bound state solutions for stationary Schrödinger systems of the form −Δu+V(x)u=K(x)Fu(u,v)in RN,−Δv+V(x)v=K(x)Fv(u,v)in RN, where N⩾3, V and K are bounded continuous nonnegative functions, and F(u,v) is a C1 and p-homogeneous function with 2<p<2N/(N−2). We give a special attention to the case when V may eventually vanishes. Our arguments are based on penalization techniques, variational methods and Moser iteration scheme.

Keywords: elliptic systems, variational methods, vanishing potential, nonlinear Schrödinger equations, bounded states
