OverviewSub-Riemannian geometry (also known as Carnot geometry in France, and non-holonomic Riemannian geometry in Russia) has been a full research domain for fifteen years, with motivations and ramifications in several parts of pure and applied mathematics, namely: * control theory * classical mechanics * Riemannian geometry (of which sub-Riemannian geometry constitutes a natural generalization, and where sub-Riemannian metrics may appear as limit cases) * diffusion on manifolds * analysis of hypoelliptic operators * Cauchy-Riemann (or CR) geometry. Although links between these domains had been foreseen by many authors in the past, it is only in recent years that sub- Riemannian geometry has been recognized as a possible common framework for all these topics. This book provides an introduction to sub-Riemannian geometry and presents the state of the art and open problems in the field. It consists of five coherent and original articles by the leading specialists: * Andre Bellaiche: The tangent space in sub-Riemannian geometry * Mikhael Gromov: Carnot-Caratheodory spaces seen from within * Richard Montgomery: Survey of singular geodesics * Hector J. Sussmann: A cornucopia of four-dimensional abnormal sub-Riemannian minimizers * Jean-Michel Coron: Stabilization of controllable systems Full Product DetailsAuthor: Andre Bellaiche , Jean-Jaques RislerPublisher: Birkhauser Verlag AG Imprint: Birkhauser Verlag AG Edition: Softcover reprint of the original 1st ed. 1996 Volume: 144 Dimensions: Width: 15.50cm , Height: 2.10cm , Length: 23.50cm Weight: 0.616kg ISBN: 9783034899468ISBN 10: 3034899467 Pages: 398 Publication Date: 18 October 2011 Audience: Professional and scholarly , Professional & Vocational Format: Paperback Publisher's Status: Active Availability: In Print  This item will be ordered in for you from one of our suppliers.
