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…
