Abstract:
I will present some recent results on control and stabilization for the wave and Schr?dinger equations, using semiclassical analysis. I will focus on two simple operatros: the flat Laplacian on torus and the Bouendi-Grushin operator. The talk is a general introduction. I will first discuss the links of concepts in the control theory for linear evolution equations (such as the exact controllability, observability, stabilization) and resolvent estimates (for stationary problems). Next, a quick review for some classical results will be given, in order to motivate the study of geometric effects on control problems.
