有界区域和无限板上磁薛定谔算子的部分数据反问题

Inverse problems with partial data for a magnetic Schrödinger operator in an infinite slab and on a bounded domain

Katsiaryna Krupchyk, Matti Lassas, Gunther Uhlmann

摘要:

本文研究磁薛定谔算子的部分数据反边值问题。在$R^n$,$n\ge 3$中无限平板的情况下,我们建立了当Dirichlet和Neumann数据在平板的不同边界超平面上或在同一超平面上给出时,磁场和电势可以唯一确定。这是对[41]的结果的推广,该结果是针对没有磁势的薛定谔算子得到的。在$R^n$,$n\ge 3$中有界区域的情况下,推广了[2]的结果,给出了在边界的两个任意开子集上由Dirichlet和Neumann数据确定磁场和电势的唯一性,条件是边界附近的磁势和电势是已知的.推广[31]的结果,我们还得到了磁薛定谔算子的唯一性结果,当Dirichlet和Neumann数据在边界的同一部分上已知时,假设边界的不可达部分是超平面的一部分。

英文摘要:

In this paper we study inverse boundary value problems with partial data for the magnetic Schrödinger operator. In the case of an infinite slab in $R^n$, $n\ge 3$, we establish that the magnetic field and the electric potential can be determined uniquely, when the Dirichlet and Neumann data are given either on the different boundary hyperplanes of the slab or on the same hyperplane. This is a generalization of the results of [41], obtained for the Schrödinger operator without magnetic potentials. In the case of a bounded domain in $R^n$, $n\ge 3$, extending the results of [2], we show the unique determination of the magnetic field and electric potential from the Dirichlet and Neumann data, given on two arbitrary open subsets of the boundary, provided that the magnetic and electric potentials are known in a neighborhood of the boundary. Generalizing the results of [31], we also obtain uniqueness results for the magnetic Schrödinger operator, when the Dirichlet and Neumann data are known on the same part of the boundary, assuming that the inaccessible part of the boundary is a part of a hyperplane.
