Energy decay estimates for an axially travelling string damped at one end
Seyf Eddine Ghenimi, Abdelmouhcene Sengouga
We study the small vibrations of an axially travelling string with a dashpoint damping at one end. The string is modelled by a wave equation in a time-dependent interval with two e…

Free vibrations of axially moving strings: Energy estimates and boundary observability
Seyf Eddine Ghenimi, Abdelmouhcene Sengouga
We study the small vibrations of axially moving strings described by a wave equation in an interval with two endpoints moving in the same direction with a constant speed. The solut…
