DESCRIPTION:Title: <a href="https://researchseminars.org/talk/IMS/35/">Con
 trol for wave equations: revisiting the geometric control condition 30 yea
 rs later</a>\nby Nicolas Burq (Institut de Mathématiques d'Orsay) as part
  of PDE seminar via Zoom\n\n\nAbstract\nFollowing the pioneering work by B
 ardos-Lebeau and Rauch\, the property of controllability for the wave equa
 tion has been intensively studied\, mainly in a smooth framework (smooth m
 etric and smooth domain). In this lecture\, and I  shall present some new 
 results on observability/control for the wave equation with rough coeffici
 ents. This question leads to some interesting ODE questions for vector fie
 lds with only continuous coefficients.\n\n\nThis is joint work B. Dehman (
 Université Tunis El Manar) and  J. Le Rousseau (Université Paris 13).\n
