摘要:

该文研究如下一类临界薛定谔-泊松方程{Δu+λV(x)u+ϕu=μ|u|p2u+|u|4u,Δϕ=u2,xR3,xR3,

其中λ>0μ>0是两个参数,p46V满足一些势井条件.当参数λ充分大时,利用变分法证明了基态解的存在性,以及随着λ时,这些解的渐近行为.另外,在参数λ充分大和μ充分小时,利用Ljusternik-Schnirelmann理论,到了多重解的存在性定理.

关键词: 临界指标, 渐近行为, 多重解

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
