This section is devoted to the proof of the main result of this article, Theorem 1.2, that is the null-controllability of the Kolmogorov equation (1.1) in the whole phase space with

In Proposition 2 below, we prove that a very simple histogram based estimator possesses this property, while in Proposition 3, we establish that this is also true for the more

We also show the related but easier results that if G is a path, then for any matrix M e M(G) of corank 1, the null space kerM of M yields an embedding of G in the line; furthermore,

In [9,11,12] Klainerman and Rodnianski developed systematic methods to prove that, on truncated null hypersur- faces initiating from a 2-D surface diffeomorphic to S 2 , within

(limit) theta-characteristic is the projective dimension of the space of sections of the line bundle or torsion-free rank-one sheaf.. We shall assume that the reader

As far as we are aware, this is the first proof of the null-controllability of the heat equation with arbitrary control domain in a n -dimensional open set which avoids
