Null controllability of Grushin-type operators in dimension two

K. Beauchard, P. Cannarsa, R. Guglielmi

We study the null controllability of the parabolic equation associated with the Grushin-type operator $A={\partial }_x^2+|x{|}^{2\gamma }{\partial }_y^2,(\gamma >0),$ in the rectangle $Ω=(-1,1)\tim…
