Title: The block moment method in action

Abstract: The main objective of this talk is to present a new null-controllability result for a 2D system of two coupled parabolic equations, with different diffusion coefficients,
under the action of only one boundary control. We prove, in particular, that short-time controllability holds for this problem whereas it is not necessarily the case for the similar system in 1D.
The proof appears to be a somehow unexpected application of the block moment method, that I will describe during the talk.
