An inverse spectral problem on surfaces

open access: yesCommentarii Mathematici Helvetici, 2006
The purpose of this paper is to prove how the positivity of some operators on a Riemannian surface gives informations on the conformal type of the surface (the operators considered here are of the form \Delta+\lambda\mathcal{K} where

Multidimensional Borg-Levinson inverse spectral problems

open access: yes, 2020
This text deals with multidimensional Borg-Levinson inverse theory. Its main purpose is to establish that the Dirichlet eigenvalues and Neumann boundary data of the operator −∆+q, acting in a bounded domain of R d with d 2, uniquely determine the realvalued bounded potential q.
