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 f…

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,…

On Instability Properties of the Fractional Calderón Problem
Hendrik Baers, Giovanni Covi, Angkana Rüland
We prove exponential instability properties for the fractional Calderón problem and the conductivity formulation of the fractional Calderón problem in the regime of fractional po…
