临界Schrödinger-Poisson系统的多重正界态

Multiple positive bound states for critical Schrödinger-Poisson systems

Giovanna Cerami, Riccardo Molle

摘要:

本文用变分方法证明了如下Schrödinger-Poisson系统正束缚态的存在性和多重性的一些结果:$$ \left\{ \begin{array}{l} \vspace{2mm} -Δu+V(x)u+K(x)ϕ(x)u=u^5 -Δϕ=K(x)u^2\qquad x\in\R^3 \end{array}\right.\quad\quad (SP) $$我们注意到由于$\R^3$的无界性和非线性项的临界增长,$(SP)$表现出“双重”的紧性缺乏,而在我们的假设下,$(SP)$的基态解不存在.

英文摘要:

Using variational methods we prove some results about existence and multiplicity of positive bound states of to the following Schrödinger-Poisson system: $$ \left\{ \begin{array}{l} \vspace{2mm} -Δu+V(x)u+K(x)ϕ(x)u=u^5 -Δϕ=K(x)u^2\qquad x\in\R^3 \end{array}\right.\quad\quad (SP) $$ We remark that $(SP)$ exhibits a "double" lack of compactness because of the unboundedness of $\R^3$ and the critical growth of the nonlinear term and that in our assumptions ground state solutions of $(SP)$ do not exist.
