On Weak Observability For Evolution Systems with Skew-Adjoint Generators
Kaïs Ammari, Faouzi Triki
In the paper we consider the linear inverse problem that consists in recovering the initial state in a first order evolution equation generated by a skew-adjoint operator. We studi…
Controllability of localized quantum states on infinite graphs through bilinear control fields
Kaïs Ammari, Alessandro Duca
In this work, we consider the bilinear Schrödinger equation in the Hilbert space with an infinite graph. The L…
Stability for biparabolic subalgebras of simple Lie algebras
Kais Ammari
Let K be an algebraically closed field of characteristic 0. It is well known that any quasi-reductive Lie algebra is stable. However, there are stable Lie algebras which are not qu…
Stabilization for the wave equation with singular Kelvin-Voigt damping
Kaïs Ammari, Fathi Hassine, Luc Robbiano
We consider the wave equation with Kelvin-Voigt damping in a bounded domain. The exponential stability result proposed by Liu and Rao or Tébou for that system assumes that the damp…
Fractional-feedback stabilization for a class of evolution systems
Kaïs Ammari, Fathi Hassine, Luc Robbiano
We study the problem of stabilization for a class of evolution systems with fractional-damping. After writing the equations as an augmented system we prove in this article first th…
Note on exponential and polynomial convergence for a delayed wave equation without displacement
Kaïs Ammari, Boumediène Chentouf
This note places primary emphasis on improving the asymptotic behavior of a multi-dimensional delayed wave equation in the absence of any displacement term. In the first instance,…
