磁场中分数阶薛定谔方程的反问题

An inverse problem for the fractional Schrödinger equation in a magnetic field

Giovanni Covi

摘要:

本文证明了分数阶磁薛定谔方程(FMSE)反问题的整体唯一性:有界区域中的未知电磁场在自然规范下是通过在外部的任意开子集中进行无穷多次解的测量唯一确定的.证明是基于Alessandrini的身份和龙格逼近性质,从而推广了以前的一些工作的分数拉普拉斯。此外,我们用一个简单的模型表明,FMSE涉及到一个长的跳跃随机游动的重量。

英文摘要:

This paper shows global uniqueness in an inverse problem for a fractional magnetic Schrödinger equation (FMSE): an unknown electromagnetic field in a bounded domain is uniquely determined up to a natural gauge by infinitely many measurements of solutions taken in arbitrary open subsets of the exterior. The proof is based on Alessandrini's identity and the Runge approximation property, thus generalizing some previous works on the fractional Laplacian. Moreover, we show with a simple model that the FMSE relates to a long jump random walk with weights.
