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…
Stable determination of a second order perturbation of the polyharmonic operator by boundary measurements
Nesrine Aroua, Mourad Bellassoued
In this paper, we consider the inverse boundary value problem for the polyharmonic operator. We prove that the second order perturbations are uniquely determined by the correspondi…
Stability estimate for an inverse problem for the time harmonic magnetic Schrödinger operator from the near and far field pattern
Mourad Bellassoued, Houssem Haddar, Amal Labidi
We derive conditional stability estimates for inverse scattering problems related to time harmonic magnetic Schrödinger equation. We prove logarithmic type estimates for retrieving…
Identification of unbounded electric potentials through asymptotic boundary spectral data
Mourad Bellassoued, Yavar Kian, Yosra Mannoubi +1
We prove that the real-valued electric potential of the Dirichlet Laplacian acting in a bounded domain , , is…
Stable recovery of a metric tensor from the partial hyperbolic Dirichlet to Neumann map
Mourad Bellassoued
In this paper we consider the inverse problem of determining on a compact Riemannian manifold the metric tensor in the wave equation with Dirichlet data from measured Neumann bound…
Global logarithmic stability results on the Cauchy problem for anisotropic wave equations
Mourad Choulli, Mourad Bellassoued
We discuss the Cauchy problem for anisotropic wave equations. Precisely, we address the question to know which kind of Cauchy data on the lateral boundary are necessary to guarante…
