An inverse problem of finding two time-dependent coefficients in second order hyperbolic equations from Dirichlet to Neumann map
Mourad Bellassoued, Ibtissem Ben Aïcha
In the present paper, we consider a non self adjoint hyperbolic operator with a vector field and an electric potential that depend not only on the space variable but also on the ti…
Stability estimate in the inverse scattering for a single quantum particle in an external short-range potential
Luc Robbiano, Mourad Bellassoued
In this paper we consider the inverse scattering problem for the Schr{ö}dinger operator with short-range electric potential. We prove in dimension n 2 that the knowledge of…
A Borg-Levinson theorem for magnetic Schrödinger operators on a Riemannian manifold
Mourad Bellassoued, Mourad Choulli, Dos Santos Ferreira +2
This article is concerned with uniqueness and stability issues for the inverse spectral problem of recovering the magnetic field and the electric potential in a Riemannian manifold…
Simultaneous determination of two coefficients in the Riemannian hyperbolic equation from boundary measurements
Mourad Bellassoued, Zouhour Rezig
In this paper we consider the inverse problem of determining on a compact Riemannian manifold the electric potential and the absorption coefficient in the wave equation with Dirich…
