Title: Null-controllability of parabolic-transport systems.

Abstract: We consider the null-controllabillity problem for systems of equations coupling parabolic equations and transport equations. This problem requires combining arguments adapted for parabolic equations and arguments suitable for transport equations, which are of different nature. We manage to do it for 1 dimensional, periodic boundary conditions, constant coefficients systems. Results for several particular cases of such equations were already known in the litterature, and we get this way close variants of these theorems. In this talk, we will present the ideas of our method to tackle these systems.
