Infinitely many positive solutions for Schrödinger-poisson systems with nonsymmetry potentials

Abstract

The present paper deals with a class of Schrodinger-poisson system. Under some suitable assumptions on the decay rate of the coefficients, we derive the existence of infinitely many positive solutions to the problem by using purely variational methods. Comparing to the previous works, we encounter some new challenges because of nonlocal term. By doing some delicate estimates for the nonlocal term we overcome the difficulty and find infinitely many positive solutions.
