Lipschitz stability for degenerate parabolic systems

Idriss Boutaayamou, Abdelkarim Hajjaj, Lahcen Maniar

Abstract:
In this article, we study an inverse problem for weakly degenerate coupled parabolic systems with one force. We establish Lipschitz stability for the source term from measurements of one component of the solution at a positive time and on a subset of the space domain. The key ingredient is the derivation of a Carleman-type estimate.
