Abstract:

In this paper, we study the existence and multiplicity of solutions for the Schrödinger-Poisson system 
where VC(R3, R) and KL2L with K≥ 0. Without assuming the Ambrosetti-Rabinowitz type superquadratic condition and the monotonicity of the function t→(f(x,t))/(t3), we prove the existence of infinitely many high-energy solutions by using symmetric mountain pass theorem. We also consider the case where f is sublinear and establish the existence and multiplicity.

Key words: Schrö, dinger-Poisson system, Superlinear, Sublinear, Infinitely many solutions, Variational methods
