A stabilized finite element method for inverse problems subject to the convection–diffusion equation. I: diffusion-dominated regime

The numerical approximation of an inverse problem subject to the convection–diffusion equation when diffusion dominates is studied. We derive Carleman estimates that are of a form suitable for use in numerical analysis and with explicit dependence on the Péclet number. A stabilized finite element me...
