Geometric mapping theory of the Heisenberg group, sub-Riemannian manifolds, and hyperbolic spaces
… to new notions of base-$b$ expansions and continued fractions. As a metric space, $\Heis^n$ serves as an infinitesimal model (metric tangent space) of some sub-Riemannian manifolds and allows one to study derivatives of mappings between such spaces. As a subgroup of the isometry group of …
