Null-controllability for weakly dissipative heat-like equations

Armand Koenig, Paul Alphonse

We study the null-controllability properties of heat-like equations posed on the whole Euclidean space $R^{n}$ . These evolution equations are associated with Fourier multipli…

Null-controllability properties of the generalized two-dimensional Baouendi-Grushin equation with non-rectangular control sets

Jérémi Dardé, Armand Koenig, Julien Royer

We consider the null-controllability problem for the generalized Baouendi-Grushin equation $(\partial_{t} - \partial_{x}^{2} - q (x)^{2} \partial_{y}^{2}) f = 1_{ω} u$ on a rectangular domain. Sharp…
