2-D Schrödinger-Newton方程最小作用奇解的存在性和轴对称性

Existence and axial symmetry of minimal action odd solutions for 2-D Schrödinger-Newton equation

Yang Zhang

摘要:

我们考虑下面的二维薛定谔-牛顿方程\begin{eqnarray*} \begin{cases} -Δu+u=w|u|^{p-1}u \\ -Δw=2 π|u|^p \end{cases}\text{in} \; \mathbb{R}^2 \end{eqnarray*}对于$ p \geq 2 $。利用具有Cerami紧性的变分方法,证明了极小作用奇解的存在性.通过对上半空间上的一个类似但更复杂的方程仔细地应用移动平面法,我们证明了这些解实际上是轴对称的。我们的结果部分地可以看作是文献\cite{GS}中结果在二维情形下的对应,或者是\cite{CW}中结果在奇解情形下的推广.

英文摘要:

We consider the following 2-D Schrödinger-Newton equation \begin{eqnarray*} \begin{cases} -Δu+u=w|u|^{p-1}u \\ -Δw=2 π|u|^p \end{cases}\text{in} \; \mathbb{R}^2 \end{eqnarray*} for $ p \geq 2 $. Using variational method with the Cerami compactness property, we prove the existence of minimal action odd solutions. Also by carefully applying the method of moving plane to a similar but more complex equation on the upper half space, we prove these solutions are in fact axially symmetric. Our results partially can be seen as the counterpart of results in paper \cite{GS} for the 2-D case, or the extension of the results \cite{CW} to the odd solution case.
