RT Book, Section T1 Obstruction and some approximate controllability results for the burgers equation and related problems A1 Díaz Díaz, Jesús Ildefonso A2 Casas, Eduardo AB The paper studies the approximate controllability for the Burgers equation. Due to the presence of a superlinear term, an obstruction phenomenon arises which implies a lack of approximate controllability in spaces of type L^p or $C$. However, the author is able to prove several controllability results under suitable constraints on the desired state. Finally, a necessary condition for the approximate controllability of the Navier-Stokes system on a rectangle is given.
