Geometric Differentiation: For the Intelligence of Curves and Surfaces / Edition 2

by I. R. Porteous

Overview

This is a revised and extended version of the popular first edition. Inspired by the work of Thom and Arnold on singularity theory, such topics as umbilics, ridges and subparabolic lines, all robust features of a smooth surface, which are rarely treated in elementary courses on differential geometry, are considered here in detail. These features are of immediate relevance in modern areas of application such as interpretation of range data from curved surfaces and the processing of magnetic resonance and cat-scan images. The author has included many exercises and examples to illustrate the results proved.

Editorial Reviews

"Porteous' approach is distinguished by the extreme richness of the examples he treats, and his novel emphasis on certain concepts—ridges, ribs, umbilics—where third-and-higher-order derivates are crucial. The book's illustrations are helpful and elegant...highly recommended." Choice

From the Publisher

The second edition of this textbook by Porteous (pure mathematics, U. of Liverpool), for advanced undergraduate and beginning postgraduate students of mathematics, centers on the local differential geometry of smooth curves and surfaces in Euclidean space. The text has been revised and expanded, and includes a new chapter incorporating the work of Richard Morris, Mike Puddephat and Tom Barrick on what happens to flexcords at generic and near-generic births of umbilics, and the work of Bill Bruce, Peter Giblin and Farid Tari, using the machinery of singularity theory, and also includes new information on the geometry of curves on 2 and new results on curves and surfaces in 3. The material is relevant to scientists and engineers in a variety of disciplines. Annotation c. Book News, Inc., Portland, OR (booknews.com)
