Abstract
We consider the mixed problem on the exterior of the unit ball in for a defocusing Schrödinger equation with a power nonlinearity with zero boundary data. Assuming that the initial data are non-radial, sufficiently small perturbations of large radial initial data, we prove that for all powers the solution exists for all times, its Sobolev norms do not inflate, and the solution is unique in the energy class.

摘要
我们考虑单元球外部的混合问题 对于具有功率非线性的散焦薛定谔方程 零边界数据。假设初始数据是非径向的,大径向初始数据的扰动足够小,我们证明对于所有幂 该解一直存在,其 Sobolev 范数不会膨胀,并且该解在能量类中是唯一的。
