摘要
This Note deals with the controllability of Stokes and Navier-Stokes systems with distributed controls with support in possibly small subdomains. We first present a new global Carleman inequality for the solutions to Stokes-like systems that leads to the null controllability at any time T > 0. Then, we present a local result concerning exact controllability to trajectories of the Navier-Stokes system. (C) 2004 Academie des sciences. Published by Elsevier SAS. All rights reserved.
