Journal ArticleDOI
Uniqueness and reconstruction for the fractional Calderón problem with a single measurement
TL;DR: In this article, the authors show global uniqueness in the fractional Calderon problem with a single measurement and with data on arbitrary disjoint subsets of the exterior, and give a constructive procedure for determining an unknown potential from a single exterior measurement, based on constructive versions of the unique continuation result.
Journal ArticleDOI
The fractional Calderón problem: Low regularity and stability
Angkana Rüland,Mikko Salo +1 more
TL;DR: The Calderon problem for the fractional Schrodinger equation has been shown to enjoy logarithmic stability under suitable a priori bounds for potentials in scale-invariant L p or negative order Sobolev spaces.
Journal ArticleDOI
Unique Continuation for Fractional Schrödinger Equations with Rough Potentials
TL;DR: In this paper, the weak and strong unique continuation principle for fractional Schrodinger equations with scaling critical and rough potentials via Carleman estimates was dealt with, and the authors extended the weak continuation principle to the case of scaling critical potentials.
Journal ArticleDOI
The Calderón problem for the fractional Schrödinger equation with drift
TL;DR: In this paper, the Calderon problem for the fractional Schrodinger equation with drift is studied and it is shown that the unknown drift and potential in a bounded domain can be determined simultaneously and uniquely by an infinite number of exterior measurements.
