Indirect stabilization of nonlinear coupled wave equations in the presence of time delay or indefinite damping
Alhabib Moumni, Cristina Pignotti, Jawad Salhi +1
This paper explores the exponential stability of two nonlinear wave equations coupled through their velocities. The analysis is divided into two main cases. First, we consider a sy…
Theoretical and numerical indirect stabilization of coupled wave equations with a single time-delayed damping
Alhabib Moumni, Mohamed Mehdaoui, Jawad Salhi +1
The focal point of this paper is to theoretically investigate and numerically validate the effect of time delay on the exponential stabilization of a class of coupled hyperbolic sy…
Boundary controllability for a coupled system of degenerate/singular parabolic equations
Brahim Allal, Abdelkarim Hajjaj, Jawad Salhi +1
In this paper we study the boundary controllability for a system of two coupled degenerate/singular parabolic equations with a control acting on only one equation. We analyze both…
Null controllability for a degenerate population equation with memory
B. Allal, G. Fragnelli, J. Salhi
In this paper we consider the null controllability for a population model depending on time, on space and on age. Moreover, the diffusion coefficient degenerate at the boundary of…
Null controllability for the singular heat equation with a memory term
Brahim Allal, Genni Fragnelli, Jawad Salhi
In this paper we focus on the null controllability problem for the heat equation with the so-called inverse square potential and a memory term. To this aim, we first establish the…
