Determination of first order perturbation for bi-harmonic operator by asymptotic boundary spectral data
Nesrine Aroua, Mourad Bellassoued
This article deals with the multidimensional Borg-Levinson theorem for perturbed bi-harmonic operator. More precisely, in a bounded smooth domain of , with , we pro…

Stability estimates for the anisotropic wave equation from the Dirichlet-to-Neumann map
Mourad Bellassoued, David Dos Santos Ferreira
In this article we seek stability estimates in the inverse problem of determining the potential or the velocity in a wave equation in an anisotropic medium from measured Neumann bo…
