具有局部微扰的Choquard方程归一化基态的不存在性、存在性和对称性

Nonexistence, existence and symmetry of normalized ground states to Choquard equations with a local perturbation

Xinfu Li

摘要:

本文研究了具有指定质量\begin{equation*} \int_{\mathbb{R}^N}|u|^2dx=a^2. \end{equation*}的局部微扰\begin{equation*} -Δu=λu+(I_α\ast|u|^p)|u|^{p-2}u+μ|u|^{q-2}u,\ x\in \mathbb{R}^{N} \end{equation*}的Choquard方程。对于$L^2$ -临界或$L^2$ -超临界微扰$μ|u|^{q-2}u$,利用山路引理、Pohožaev约束方法、Schwartz对称化重排和一些极化理论,证明了归一化基态的不存在性、存在性和对称性。特别是,我们的结果涵盖了Hardy-Littlewood-Sobolev上临界指数的情况$p=(N+α)/(N-2)$。我们的结果是\cite{{Li 2021-4},{Soave JFA},{Wei-Wu 2021}}结果的非局部对应。

英文摘要:

We study the Choquard equation with a local perturbation \begin{equation*} -Δu=λu+(I_α\ast|u|^p)|u|^{p-2}u+μ|u|^{q-2}u,\ x\in \mathbb{R}^{N} \end{equation*} having prescribed mass \begin{equation*} \int_{\mathbb{R}^N}|u|^2dx=a^2. \end{equation*} For a $L^2$-critical or $L^2$-supercritical perturbation $μ|u|^{q-2}u$, we prove nonexistence, existence and symmetry of normalized ground states, by using the mountain pass lemma, the Pohožaev constraint method, the Schwartz symmetrization rearrangements and some theories of polarizations. In particular, our results cover the Hardy-Littlewood-Sobolev upper critical exponent case $p=(N+α)/(N-2)$. Our results are a nonlocal counterpart of the results in \cite{{Li 2021-4},{Soave JFA},{Wei-Wu 2021}}.
