Any sub-Riemannian Metric has Points of Smoothness
Andrei Agrachev
We prove the result stated in the title; it is equivalent to the existence of a regular point of the sub-Riemannian exponential mapping. We also prove that the metric is analytic o…

The intrinsic hypoelliptic Laplacian and its heat kernel on unimodular Lie groups
Andrei Agrachev, Ugo Boscain, Jean-Paul Gauthier +1
We present an invariant definition of the hypoelliptic Laplacian on sub-Riemannian structures with constant growth vector, using the Popp's volume form introduced by Montgomery. Th…
