由可容许几何中的Cauchy数据确定无界位势

Determining an unbounded potential from Cauchy data in admissible geometries

David Dos Santos Ferreira, Carlos E. Kenig, Mikko Salo

摘要:

在Dos Santos Ferreira,Kenig,Salo和Uhlmann的前一篇文章中,考虑了在某些容许几何中,即在紧黎曼流形上的各向异性反问题,其边界共形地嵌入在欧氏直线和简单流形的乘积中。特别地,证明了薛定谔方程中的有界光滑势是由n维\geq 3中的Dirichlet-to-Neumann映射唯一确定的.在这篇文章中,我们将这个结果推广到无界势的情况,即那些在Ln/2。在这个过程中,我们得到Lp Carleman估计与限制Carleman权重类似的Jerison-Kenig和Kenig-Ruiz-Sogge的欧几里得估计。

英文摘要:

In a previous article of Dos Santos Ferreira, Kenig, Salo and Uhlmann, anisotropic inverse problems were considered in certain admissible geometries, that is, on compact Riemannian manifolds with boundary which are conformally embedded in a product of the Euclidean line and a simple manifold. In particular, it was proved that a bounded smooth potential in a Schrödinger equation was uniquely determined by the Dirichlet-to-Neumann map in dimensions n \geq 3. In this article we extend this result to the case of unbounded potentials, namely those in Ln/2. In the process, we derive Lp Carleman estimates with limiting Carleman weights similar to the Euclidean estimates of Jerison-Kenig and Kenig-Ruiz-Sogge.
