Exact boundary control for the wave equa
✍ W.D. Bastos; J. Ferreira πŸ“‚ Article πŸ“… 1999 πŸ› Elsevier Science 🌐 English βš– 231 KB

We establish exact boundary controllability for the wave equation in a polyhedral domain where a part of the boundary moves slowly with constant speed in a small interval of time. The control on the moving part of the boundary is given by the conormal derivative associated with the wave operator whi
