Stabilization of weakly coupled viscoelastic Kirchhoff plate and wave equations
Zayd Hajjej, Mohammad Akil, Mohamed Balegh +1
In this paper, we consider a weakly coupled system consisting of a viscoelastic Kirchhoff plate equation involving free boundary conditions and the viscoelastic wave equation with…
Exponential Stability and exact controllability of a system of coupled wave equations by second order terms (via Laplacian) with only one non-smooth local damping
Mohammad Akil, Mohamed Balegh, Zayd Hajjej
The purpose of this work is to investigate the exponential stability of a second order coupled wave equations by laplacian with one locally internal viscous damping. Firstly, using…
Stability and instability results of the Kirchhoff plate equation with delay terms on boundary or dynamical boundary controls
Mohammad Akil, Haidar Badawi, Mohamed Balegh +1
In this paper, we consider the Kirchhoff plate equation with delay terms on the boundary control are added (see system \eqref{p5-2.1} below). we give some instability examples of s…
Uniformly exponentially stable approximations for a class of damped systems with unbounded feedbacks
Zayd Hajjej, Mohamed Balegh
In this paper we study time semi-discrete approximations of a class of exponentially stable infinite dimensional systems with unbounded feedbacks. It has recently been proved that…
