Boris Kruglikov "Non-holonomic Riemannian geometry".
This time we discuss the notions of derived flag and Tanaka invariant of a distribution. We present the concept of tangent space of a metric space due to Gromov and review the result in this direction from sub-Riemannian geometry. We study Lie algebras bundles over a manifold and overview the classification problem.
