Definition 4.12: Let (([N.sub.1]), [d.sub.1]) and (([N.sub.2], *), [d.sub.2]) be NT metric spaces, [mathematical expression not reproducible] and [mathematical expression not reproducible] be NT metric topologies.
They give a unified definition of curvature that applies to a wide class of geometric structures whose geodesics arise from optimal control problems, including Riemannian, sub-Riemannian, Finsler, and sub-Finsler spaces, but pay special attention to the sub-Riemannian (or Carnot-Caratheodory) metric spaces. Their construction of curvature is direct and naive, they say, similar to the original approach of Riemann.
