Weak Observability Characterization for Abstract Wave Equations
Nisrine Charaf, Faouzi Triki
The paper studies weak observability for abstract wave equations generated by skew‑adjoint operators, providing a spectral characterization via a new notion of spectral coercivity…

On exact Observability for Compactly perturbed infinite dimension system
Nisrine Charaf, Faouzi Triki
In this paper, we study the observability of compactly perturbed infinite dimensional systems. Assuming that a given infinite-dimensional system with self-adjoint generator is exac…
