Abstract:

In this paper, we consider the following critical Schrödinger-Poisson system {Δu+λV(x)u+ϕu=μ|u|p2u+|u|4u,Δϕ=u2,xR3,xR3,

where λ,μ are two positive parameters, p(4,6) and V satisfies some potential well conditions. By using the variational arguments, we prove the existence of ground state solutions for λ large enough and μ>0, and their asymptotical behavior as λ. Moreover, by using Lusternik-Schnirelmann theory, we obtain the existence of multiple solutions if λ is large and μ is small.

Key words: Critical exponent, Asymptotical behavior, Multiple solutions
