On the transfer of stability from the local to the fractional anisotropic Calderón problem with exterior measurements

Hendrik Baers, Angkana Rüland

We study the quantitative transfer of uniqueness from the classical to the fractional Calderón problem with exterior data. This allows us to deduce the first stability estimates fo…

Transfer of Stability from the Classical to the Fractional Anisotropic Calderón Problem

Hendrik Baers, Angkana Rüland

We discuss two spectral fractional anisotropic Calderón problems with source-to-solution measurements and their quantitative relation to the classical Calderón problem. Firstly, we…

Boundary Reconstruction for the Anisotropic Fractional Calderón Problem

Xiaopeng Cheng, Angkana Rüland

In this article, we provide a boundary reconstruction result for the anisotropic fractional Calderón problem and its associated degenerate elliptic extension into the upper half pl…

Fractional anisotropic Calderón problem with external data

Ali Feizmohammadi, Tuhin Ghosh, Katya Krupchyk +3

In this paper, we solve the fractional anisotropic Calderón problem with external data in the Euclidean space, in dimensions two and higher, for smooth Riemannian metrics that agre…

On a -Structure in Geometrically Linearized Elasticity: Qualitative and Quantitative Analysis and Numerical Simulations

Roman Indergand, Dennis Kochmann, Angkana Rüland +2

We study the rigidity properties of the -structure for the symmetrized gradient from \cite{BFJK94} qualitatively, quantitatively and numerically. More precisely, we complement…
