Resumo

In this paper we consider the following Schrodinger-Poisson system in the whole R-3, [-Delta u + u + lambda phi u = f (u) in R-3, -Delta phi = u(2) in R-3, where lambda > 0 and the nonlinearity f is ``asymptotically cubic{''} at infinity. This implies that the nonlocal term phi u and the nonlinear term f(u) are, in some sense, in a strict competition. We show that the system admits a least energy sign-changing and radial solution obtained by minimizing the energy functional on the so-called modal Nehari set. (C) 2019 Elsevier Inc.
