H{ö}lder stability in determining the potential and the damping coefficient in a wave equation
Kais Ammari, Mourad Choulli, Faouzi Triki
We improve the preceding results obtained by the first and the second authors in [3]. They concern the stability issue of the inverse problem that consists in determining the poten…
Determining a boundary coefficient in a dissipative wave equation: Uniqueness and directional lipschitz stability
Mourad Choulli, Kaïs Ammari
We are concerned with the problem of determining the damping boundary coefficient appearing in a dissipative wave equation from a single boundary measurement. We prove that the uni…
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…
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…
