Stability of an abstract-wave equation with delay and a Kelvin-Voigt damping
Kais Ammari, Serge Nicaise, Cristina Pignotti
In this paper we consider a stabilization problem for the abstract-wave equation with delay. We prove an exponential stability result for appropriate damping coefficient. The proof…
Remark on stabilization of second order evolution equations by unbounded dynamic feedbacks and applications
Zainab Abbas, Kais Ammari, Denis Mercier
In this paper we consider second order evolution equations with unbounded dynamic feedbacks. Under a regularity assumption we show that observability properties for the undamped pr…
Rate of decay of some Petrowsky-like dissipative systems
Kais Ammari, Mouez Dimassi, Maher Zerzeri
In this paper, we show that the fastest decay rate for some Petrowsky-like dissipative systems is given by the supremum of the real part of the spectrum of the infinitesimal genera…
Boundary feedback stabilization of a chain of serially connected strings
Kais Ammari, Denis Mercier
We consider N strings connected to one another and forming a particular network which is a chain of strings. We study a stabilization problem and precisley we prove that the energy…
Interior feedback stabilization of wave equations with dynamic boundary delay
Kaïs Ammari, Stéphane Gerbi
In this paper we consider an interior stabilization problem for the wave equation with dynamic boundary delay.We prove some stability results under the choice of damping operator.…
Logarithmic stability in determining two coefficients in a dissipative wave equation. Extensions to clamped Euler-Bernoulli beam and heat equations
Kaïs Ammari, Mourad Choulli
We are concerned with the inverse problem of determining both the potential and the damping coefficient in a dissipative wave equation from boundary measurements. We establish stab…
