Most purely mathematical books on Riemannian geometry do not treat the pseudo-Riemannian case (although many results are exactly the same). The principal special cases are Riemannian geometry, where the metric is positive definite, and Lorentz geometry. TABLE OF CONTENTS 1.

This classic text serves as a tool for self-study; it is also used as a basic text for undergraduate courses in differential geometry. From the theoretical point of view, sub-Riemannian geometry is the geometry underlying the theory of hypoelliptic operators and degenerate diffusions on manifolds. The goal of di erential geometry is to study the geometry and the topology of manifolds using techniques involving di erentiation in one way or another.
