Quantitative Fattorini-Hautus test and minimal null control time for parabolic problems
F. Ammar Khodja, A. Benabdallah, M. González-Burgos +1
This paper investigates the link between the null controllability property for some abstract parabolic problems and an inequality that can be seen as a quantified Fattorini-Hautus…

Carleman Estimates and null controllability of coupled degenerate systems
E. M. Ait Ben Hassi, F. Ammar Khodja, A. Hajjaj +1
In this paper, we study the null controllability of weakly degenerate coupled parabolic systems with two different diffusion coefficients and one control force. To obtain this aim,…
