Control of the Grushin equation: non-rectangular control region and minimal time

Michel Duprez, Armand Koenig

This paper is devoted to the study of the internal null-controllability of the Grushin equation. We determine the minimal time of controllability for a large class of non-rectangul…

Lack of null-controllability for the fractional heat equation and related equations

Armand Koenig

We consider the equation $(\partial_{t} + ρ (- Δ)) f (t, x) = 1_{ω} u (t, x)$ , $x \in R$ or $T$ . We prove it is not null-controllable if $ρ$ is analytic on a coni…
