Uniformly exponentially stable approximations for a class of damped systems
(Journal des Mathematiques Pures et Appliquees, 2009-12-31)
We consider time semi-discrete approximations of a class of exponentially stable infinite-dimensional systems modeling, for instance, damped vibrations. It has recently been proved that for time semi-discrete systems, due ...
Stabilization of the wave equation on 1-D networks
(SIAM Journal on Control and Optimization, 2009-12-31)
In this paper we study the stabilization of the wa ve equation on general 1-d networks. For that, we transfer known observability results in the context of control problems of conservative systems (see [R. Dáger and E. ...
