圆柱形背景下薛定谔算符的磁场重建

Reconstruction of the magnetic field for a Schrödinger operator in a cylindrical setting

Daniel Campos

摘要:

在这篇论文中,我们考虑了包含在无限圆柱流形中的紧致区域上的磁薛定谔逆问题。我们表明,在一定的条件下的电磁势,我们可以恢复的磁场从边界测量的建设性的方式。这个过程的一个基本工具是磁薛定谔算子的全局Carleman估计。我们通过将磁算子本质上共轭到拉普拉斯算子中,并使用Kenig-Salo-Uhlmann在各向异性环境中证明的Carleman估计来证明这一点,参见[KSU 11 a]。共轭是通过伪微分算子的圆柱,我们开发的必要结果。尝试这个问题的主要动机是关于磁薛定谔算子的以下结果:第一,在[DSFKSU 09]中圆柱设置中唯一性问题的解决方案,第二,[Sal 06]中欧几里得设置中的重建算法。我们还将从[KSU 11b]中的圆柱形设置中的电势重建中借鉴想法。这两个新结果部分回答了Carleman估计问题(问题4.3)。提出的[Sal 13]和重建磁薛定谔算子中提到的介绍[KSU 11b]。据我们所知,这是第一个全球Carleman估计和重建程序的磁薛定谔算子在圆柱设置。

英文摘要:

In this thesis we consider a magnetic Schrödinger inverse problem over a compact domain contained in an infinite cylindrical manifold. We show that, under certain conditions on the electromagnetic potentials, we can recover the magnetic field from boundary measurements in a constructive way. A fundamental tool for this procedure is a global Carleman estimate for the magnetic Schrödinger operator. We prove this by conjugating the magnetic operator essentially into the Laplacian, and using the Carleman estimates for it proven by Kenig-Salo-Uhlmann in the anisotropic setting, see [KSU11a]. The conjugation is achieved through pseudodifferential operators over the cylinder, for which we develop the necessary results. The main motivations to attempt this question are the following results concerning the magnetic Schrödinger operator: first, the solution to the uniqueness problem in the cylindrical setting in [DSFKSU09], and, second, the reconstruction algorithm in the Euclidean setting from [Sal06]. We will also borrow ideas from the reconstruction of the electric potential in the cylindrical setting from [KSU11b]. These two new results answer partially the Carleman estimate problem (Question 4.3.) proposed in [Sal13] and the reconstruction for the magnetic Schrödinger operator mentioned in the introduction of [KSU11b]. To our knowledge, these are the first global Carleman estimates and reconstruction procedure for the magnetic Schrödinger operator available in the cylindrical setting.
