分数阶薛定谔方程的Calderón问题

The Calderón problem for the fractional Schrödinger equation

Tuhin Ghosh, Mikko Salo, Gunther Uhlmann

摘要:

我们证明了分数阶薛定谔方程反问题的全局唯一性:有界区域中的未知势由解的外部测量唯一确定。我们还显示了全球唯一性的部分数据的问题,其中的测量是在任意开放的,可能不相交的,外部的子集。结果适用于任何维度的$\geq 2$,并基于一个强大的近似性质的分数方程,扩展早期的工作。非局部方程的这一特性使得相关反问题的分析与传统的Calderón问题完全不同。

英文摘要:

We show global uniqueness in an inverse problem for the fractional Schrödinger equation: an unknown potential in a bounded domain is uniquely determined by exterior measurements of solutions. We also show global uniqueness in the partial data problem where the measurements are taken in arbitrary open, possibly disjoint, subsets of the exterior. The results apply in any dimension $\geq 2$ and are based on a strong approximation property of the fractional equation that extends earlier work. This special feature of the nonlocal equation renders the analysis of related inverse problems radically different from the traditional Calderón problem.
