Observability properties of the homogeneous wave equation on a closed manifold
Emmanuel Humbert, Yannick Privat, Emmanuel Trélat
We consider the wave equation on a closed Riemannian manifold. We observe the restriction of the solutions to a measurable subset along a time interval with . It…

Geometric control condition for the wave equation with a time-dependent observation domain
Jérôme Le Rousseau, Gilles Lebeau, Peppino Terpolilli +1
We characterize the observability property (and, by duality, the controllability and the stabilization) of the wave equation on a Riemannian manifold with or without boundary,…
