Title: Homogeneous geodesics in sub-Riemannian geometry

Abstract:
We study homogeneous geodesics of sub-Riemannian manifolds, i.e., geodesics that are orbits of one-parametric subgroups of isometries. We obtain a criterion for a geodesic to be homogeneous in terms of its initial momentum. We discuss some examples of geodesic orbit sub-Riemannian manifolds (that means all geodesics are homogeneous) and prove that Carnot groups of step more than 2 can not be geodesic orbit. We prove that the geodesic flow for geodesic orbit sub-Riemannian manifold is integrable in non-commutative sense.
