Problèmes aux limites non classiques pour équations d’évolution
We study the wave equation in a bounded domain subject to Cauchy data on , or on part of . Tools from the theory of optimal control are used. We use in particular the HUM theory, introduced in J. L. Lions (1986, 1988) for the problem of exact controllability.
