摘要:

该文讨论以下带有位势V的薛定谔-泊松(Schrödinger-Poisson)系统
u+λVu+φu=f(x,u),x∈R3
φ=u2,x∈R3
其中λ≥1是一个参数,位势函数VC(R3,R+)满足比较一般的假设.当非线性项f在无穷远点是超四次的,并且空间嵌入缺乏紧性时,该文讨论了参数λ≥1充分大时问题解的存在性与多解性.也考虑了非线性性项f满足一般的次线性假设时问题无穷多个解的存在性.

关键词: Schrödinger-Poisson 系统, 位势, 变分法, 超四次, 次线性

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
