Cartan for Beginners: Differential Geometry via Moving Frames and Exterior Differential Systems, Second Edition
Share this pageThomas A. Ivey; Joseph M. Landsberg
Two central aspects of Cartan's approach to
differential geometry are the theory of exterior differential systems
(EDS) and the method of moving frames. This book presents thorough and
modern treatments of both subjects, including their applications to
both classic and contemporary problems in geometry. It begins with the
classical differential geometry of surfaces and basic Riemannian
geometry in the language of moving frames, along with an elementary
introduction to exterior differential systems. Key concepts are
developed incrementally, with motivating examples leading to
definitions, theorems, and proofs.
Once the basics of the methods are established, the authors develop
applications and advanced topics. One notable application is to
complex algebraic geometry, where they expand and update important
results from projective differential geometry. As well, the book
features an introduction to \(G\)-structures and a treatment of
the theory of connections. The techniques of EDS are also applied to
obtain explicit solutions of PDEs via Darboux's method, the method of
characteristics, and Cartan's method of equivalence.
This text is suitable for a one-year graduate course in
differential geometry, and parts of it can be used for a one-semester
course. It has numerous exercises and examples throughout. It will
also be useful to experts in areas such as geometry of PDE systems and
complex algebraic geometry who want to learn how moving frames and
exterior differential systems apply to their fields.
The second edition features three new chapters: on Riemannian
geometry, emphasizing the use of representation theory; on the latest
developments in the study of Darboux-integrable systems; and on
conformal geometry, written in a manner to introduce readers to the
related parabolic geometry perspective.
Readership
Graduate students and researchers interested in differential geometry, in particular, in exterior systems and the moving frames method and in its applications in algebraic geometry, PDE, and other areas of mathematics
Reviews & Endorsements
[T]his book, like the first edition, is an excellent source for graduate students and professional mathematicians who want to learn about moving frames and G-structures in trying to understand differential geometry.
