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

Analysis of PDEs 2019-01-08 v2

Abstract

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-rectangular control region. We establish the positive result thanks to the fictitious control method and the negative one by interpreting the associated observability inequality as an L2L^2 estimate on complex polynomials.
