A Local-to-Global Propagation Principle for Dirichlet-to-Neumann Maps
Thierry Daudé, Alberto Enciso, Bernard Helffer +2
We establish four local-to-global propagation results for Dirichlet--to--Neumann maps. Our first two results are proved in the general setting of smooth compact Riemannian manifold…
Stability in the anisotropic Calderón problem for Painlevé-Liouville Riemannian manifolds
Thierry Daudé, Niky Kamran, François Nicoleau
We study the question of stability of the global and partial anisotropic Calderón inverse problems for the class of Painlevé-Liouville Riemannian manifolds, that is compact -dim…
Inverse problems for the Bakry-Émery Laplacian on manifolds with boundary -- uniqueness and non-uniqueness
Jack Borthwick, Niky Kamran
We study the questions of uniqueness and non-uniqueness for a pair of closely related inverse problems for the Bakry-Émery Laplacian on a smooth compact and orien…
Global counterexamples to uniqueness for a Calderón problem with conductivities
Thierry Daudé, Bernard Helffer, Niky Kamran +1
Let , , be a fixed smooth bounded domain, and let be a smooth conductivity in . Consider a non-zero frequency which does not belong to…
