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…
Controllability for a degenerate cascade system
Idriss Boutaayamou, Genni Fragnelli
In this paper we consider a cascade system in non divergence form which models the interaction between two different species, the first one can be seen as a predator and the other…
Controllability for a population equation with interior degeneracy
Genni Fragnelli
We deal with a degenerate model in divergence form describing the dynamics of a population depending on time, on age and on space. We assume that the degeneracy occurs in the inter…
Null controllability for a degenerate population model in divergence form via Carleman estimates
G. Fragnelli
In this paper we consider a degenerate population equation in divergence form depending on time, on age and on space and we prove a related null controllability result via Carleman…
Asymptotic parabolicity for strongly damped wave equations
Genni Fragnelli, Gisèle Ruiz Goldstein, Jerome A. Goldstein +1
For a positive selfadjoint operator on a Hilbert space, \[ \frac{d^2u}{dt}(t) + 2 F(S)\frac{du}{dt}(t) + S^2u(t)=0 \] describes a class of wave equations with strong friction o…
