摘要
This paper deals with the existence and multiplicity of nontrivial solutions for a nonlinear Schrodinger-Poisson system. Under some suitable conditions, some criteria on the existence of nontrivial solutions, including a ground state solution, two solutions and a sequence of nontrivial solutions {u(k)} with parallel to u(k)parallel to -> 0 as k -> +infinity, is established by applying the Morse theory and variational methods. Some known results in the literatures are extended and improved. (C) 2016 Elsevier Ltd. All rights reserved.
