Overview

Discrete geometry investigates combinatorial properties of configurations of geometric objects. To a working mathematician or computer scientist, it offers sophisticated results and techniques of great diversity and it is a foundation for fields such as computational geometry or combinatorial optimization. This book is primarily a textbook introduction to various areas of discrete geometry. In each area, it explains several key results and methods, in an accessible and concrete manner. It also contains more advanced material in separate sections and thus it can serve as a collection of surveys in several narrower subfields. The main topics include: basics on convex sets, convex polytopes, and hyperplane arrangements; combinatorial complexity of geometric configurations; intersection patterns and transversals of convex sets; geometric Ramsey-type results; polyhedral combinatorics and high-dimensional convexity; and lastly, embeddings of finite metric spaces into normed spaces. Jiri Matousek is Professor of Computer Science at Charles University in Prague. His research has contributed to several of the considered areas and to their algorithmic applications. This is his third book.

From the reviews: <p>MATHEMATICAL REVIEWS <p> This book, aimed at early graduate students, is an early introduction to discrete geometry understood as the study of combinatorial propertied of arrangements of points, lines, hyperplanes or convex sets in the Euclidean d-spacea ]The book can also be used as a valuable resource to researchers in various areas (for example, graph theory, computational geometry and combinatorial optimization)a ]The text is well-written and organized. The theorems are carefully proved (sometimes in several ways) and illustrated by good pictures.
