Unique Continuation, Runge Approximation and the Fractional Calderón Problem
Unique Continuation, Runge Approximation and the Fractional Calderón Problem
In these notes for the proceedings of the “Journée Équations aux Dérivées Partielles”, we survey some of the recent progress in and the interplay of unique continuation, approximation and some related nonlocal inverse problems. In particular, we discuss the qualitative and quantitative global unique continuation properties of the fractional Laplacian …
