Stabilization of second order evolution equations by a class of unbounded feedbacks
ESAIM: Control, Optimisation and Calculus of Variations, Tome 6 (2001), pp. 361-386

In this paper we consider second order evolution equations with unbounded feedbacks. Under a regularity assumption we show that observability properties for the undamped problem imply decay estimates for the damped problem. We consider both uniform and non uniform decay properties.
