Abstract: Following the pioneering work by Bardos-Lebeau and Rauch, the property of controllability for the wave equation has been intensively studied, mainly in a smooth framework (smooth metric and smooth domain). In this lecture, and I shall present some new results on observability/control for the wave equation with rough coefficients. This question leads to some interesting ODE questions for vector fields with only continuous coefficients.

This is joint work B. Dehman (Université Tunis El Manar) and J. Le Rousseau (Université Paris 13).
