Energy decay and weak observability for some evolution systems
Kaïs Ammari, Faouzi Triki
In an abstract functional framework, we investigate the equivalence between two fundamental properties: weak observability and energy decay associated with certain classes of dissi…
Delay is Necessary for a Potential to Achieve Exponential Stabilization of the Wave Equation via Internal Control
Crédo Roselin Fanou, Kaïs Ammari, Islam Boussaada
In this work, we study the stabilization of the wave equation using an internal delayed potential. Interestingly, the stabilization mechanism is entirely induced by the delay, sinc…
Regularity and stability of two coupled Euler-Bernoulli equations with a localized singular structural damping
K. Ammari, F. Hassine, L. Tebou
This paper is concerned with the study of regularity and stability properties of two Euler-Bernoulli beam equations with localized singular damping. Under suitable regularity assum…
Numerical study of a Transmission Problem in Elasticity with kind damping
Kais Ammari, Vilmos Komornik, Mauricio Sepúlveda +1
We investigate a transmission problem featuring a specific type of damping. Our primary focus is on analyzing the asymptotic behavior of the associated semigroup, $({\mathcal S}_{\…
Stability of a degenerate thermoelastic equation
Kaïs Ammari, Fathi Hassine, Luc Robbiano
This work is dedicated to the study of a linear model arising in thermoelastic rod of homogeneous material. The system is resulting from a coupling of a heat and a wave equation in…
Numerical stabilization method by switching time-delay
Kaïs Ammari, Stéphane Gerbi
In this paper, we propose a new numerical strategy for the stabilization of evolution systems. The method is based on the methodology given by Ammari, Nicaise andPignotti in ''Stab…
