关于球外的超临界薛定谔方程

On the supercritical Schrödinger equation on the exterior of a ball

Piero D'Ancona

摘要:

本文研究了具有幂非线性项$|u|^{p-1}u$的散焦薛定谔方程在$\mathbb{R}^{n}$,$n\ge2$中单位球外的混合问题.假设初始数据是非径向的,对\emph{large}径向初始数据作充分小的扰动,我们证明了对于所有幂次$p>n+6$,解总是存在的,其Sobolev范数不膨胀,且解在能量类中是唯一的.

英文摘要:

We consider the mixed problem on the exterior of the unit ball in $\mathbb{R}^{n}$, $n\ge2$, for a defocusing Schrödinger equation with a power nonlinearity $|u|^{p-1}u$, with zero boundary data. Assuming that the initial data are non radial, sufficiently small perturbations of \emph{large} radial initial data, we prove that for all powers $p>n+6$ the solution exists for all times, its Sobolev norms do not inflate, and the solution is unique in the energy class.
