Résumé
Abstract

On considère deux équations paraboliques couplées par une matrice $A (x) = q (x) A_{0}$ , où $A_{0}$ est un bloc de Jordan d'ordre 1, et contrôlées par un seul contrôle localisé en espace ou frontière. Le support du coefficient de couplage, q, et celui du contrôle peuvent être disjoints. Nous mettons en évidence un temps minimal de contrôlabilité à 0, $T_{0} (q) \in [0, + \infty]$ .

We consider two parabolic equations coupled by a matrix $A (x) = q (x) A_{0}$ , where $A_{0}$ is a Jordan block of order 1, and controlled by a single localized function, or by a single boundary control. The support of the coupling coefficient, q, and the control domain may be disjoint. We exhibit an explicit minimal time of null-controllability, $T_{0} (q) \in [0, + \infty]$ .
