Résumé
In this talk, I will present controllability results for some linear and non-linear wave equations. The linear equations will be vector-valued and at different levels of regularity. I will give the main ideas of the proof of a change of regularity result. For the non-linear equations, I will consider the case of the focusing cubic Klein-Gordon equation. I will state a local controllability result around a regular solution, and a null-controllability result for scattering solutions. In the presence of damping, I will give both a positive and a negative stabilization result. I will also provide some ideas of proofs.
