Abstract:

In this paper, we discuss the existence and multiplicity solutions to the following Schrödinger-Poisson system with potentials 
u+λVu+φu=f(x,u),x∈R3
φ=u2,x∈R3
where λ≥qslant1 is a parameter, the potential VC(R3, R+) and satisfies the more general assumptions. When f is 4-superlinear at infinity, we discuss the existence and multiplicity of solutions for λ≥1 large enough without the compactness of embedding of the work space. We also consider the existence of infinity many solutions with f satisfying the more general sublinear assumptions.

Key words: Schrödinger-Poisson system, Potential, Variational method, 4-Superlinear, Sublinear
