This talk focuses on the reconstruction of unknown coefficients in the wave equation, leveraging the power of Carleman inequalities. We aim at designing a global reconstruction algorithm for coefficients - such as time-independent potentials or wave propagation speeds - from
On présentera le modèle et on donnera des exemples où le retard déstabilise complètement le système même pour des petits retards. On donnera aussi des résultats de stabilisation exponentielle sous une condition analogue à la condition de contrôle géométrique dans
We establish a convergence result for the approximation of low-regularity solutions to time-dependent PDE systems that have an involution structure similar to Maxwell's equations and the linear wave equations. The approximation is based on an explicit Runge--Kutta (ERK) time-stepping and
