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…

A Sharp Regularity Threshold for Uniqueness in Riemannian Calderón-type Problems

Thierry Daudé, Alberto Enciso, Bernard Helffer +2

We prove a sharp regularity threshold for uniqueness in two anisotropic Calderón-type inverse problems in dimension . The main setting is the Riemannian Schrödinger problem…

Inverse Spectral Analysis of Singular Radial AKNS Operators

Damien Gobin, Benoît Grébert, Bernard Helffer +1

We study an inverse spectral problem for singular AKNS operators based on spectral data associated with two distinct values of the effective angular momentum parameter . Our m…

The Spectral Shift Function for Non-Self-Adjoint Perturbations

Vincent Bruneau, Nicolas Frantz, François Nicoleau

This paper is devoted to the definition and analysis of the spectral shift function (SSF) associated with non-self-adjoint perturbations of self-adjoint operators. Motivated by app…

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…

The spectrum of Dirichlet-to-Neumann maps for radial conductivities

Thierry Daudé, Fabricio Macià, Cristóbal Meroño +1

The problem of characterizing sequences of real numbers that arise as spectra of Dirichlet-to-Neumann (DtN) maps for elliptic operators has attracted considerable attention over th…
