摘要:

本文考虑了具有局部扰动\begin{equation*} \begin{cases} -Δu=λu+(I_α\ast|u|^{p})|u|^{p-2}u+μ|u|^{q-2}u,\ x\in \mathbb{R}^{N},\\ u\in H^1(\mathbb{R}^N),\ \int_{\mathbb{R}^N}|u|^2=a, \end{cases} \end{equation*}的上临界Choquard方程,其中$N\geq 3$,$μ>0$,$a>0$,$λ\in \mathbb{R}$,$α\in (0,N)$,$p=\bar{p}:=\frac{N+α}{N-2}$,$q\in (2,2+\frac{4}{N})$和$I_α=\frac{C}{|x|^{N-α}}$ with $C>0$ .当$μa^{\frac{q(1-γ_q)}{2}}\leq (2K)^{\frac{qγ_q-2\bar{p}}{2(\bar{p}-1)}}$,其中$γ_q=\frac{N}{2}-\frac{N}{q}$和$K$为某一正常数时,我们证明了(1)基态的存在性和轨道稳定性。(2)“第二类”解的存在性、正性、径向对称性、指数衰减和轨道不稳定性。本文将\cite{{JEANJEAN-JENDREJ},{Jeanjean-Le},{Soave JFA},{Wei-Wu 2021}}中的部分结果推广和改进到薛定谔方程。

英文摘要:

In this paper, we consider the upper critical Choquard equation with a local perturbation \begin{equation*} \begin{cases} -Δu=λu+(I_α\ast|u|^{p})|u|^{p-2}u+μ|u|^{q-2}u,\ x\in \mathbb{R}^{N},\\ u\in H^1(\mathbb{R}^N),\ \int_{\mathbb{R}^N}|u|^2=a, \end{cases} \end{equation*} where $N\geq 3$, $μ>0$, $a>0$, $λ\in \mathbb{R}$, $α\in (0,N)$, $p=\bar{p}:=\frac{N+α}{N-2}$, $q\in (2,2+\frac{4}{N})$ and $I_α=\frac{C}{|x|^{N-α}}$ with $C>0$. When $μa^{\frac{q(1-γ_q)}{2}}\leq (2K)^{\frac{qγ_q-2\bar{p}}{2(\bar{p}-1)}}$ with $γ_q=\frac{N}{2}-\frac{N}{q}$ and $K$ being some positive constant, we prove (1) Existence and orbital stability of the ground states. (2) Existence, positivity, radial symmetry, exponential decay and orbital instability of the ``second class' solutions. This paper generalized and improved parts of the results obtained in \cite{{JEANJEAN-JENDREJ},{Jeanjean-Le},{Soave JFA},{Wei-Wu 2021}} to the Schrödinger equation.
