Series: Dolciani Mathematical Expositions
Hardback (ISBN-13: 9780883853467)

A Guide to Topology is an introduction to basic topology for graduate or advanced undergraduate students. It covers point-set topology, Moore-Smith convergence and function spaces. It treats continuity, compactness, the separation axioms, connectedness, completeness, the relative topology, the quotient topology, the product topology, and all the other fundamental ideas of the subject. The book is filled with examples and illustrations. Students studying for exams will find this book to be a concise, focused and informative resource. Professional mathematicians who need a quick review of the subject, or need a place to look up a key fact, will find this book to be a useful resource too.

* A short, sharp introduction that shows readers exactly what topology is and why it is useful * Concludes with function spaces to acquaint students with the applications of the basic ideas and techniques of topology * Includes table of notation and glossary to help students get to grip with the material quickly

Lie Groups
A Problem Oriented Introduction via Matrix Groups

Series: Mathematical Association of America Textbooks
Hardback (ISBN-13: 9780883857595)

This textbook is a complete introduction to Lie groups for undergraduate students. The only prerequisites are multi-variable calculus and linear algebra. The emphasis is placed on the algebraic ideas, with just enough analysis to define the tangent space and the differential and to make sense of the exponential map. This textbook works on the principle that students learn best when they are actively engaged. To this end nearly 200 problems are included in the text, ranging from the routine to the challenging level. Every chapter has a section called ePutting the pieces togetherf in which all definitions and results are collected for reference and further reading is suggested.

* Assumes only a background in linear algebra and multi-variable calculus * Contains nearly 200 problems to promote active learning * At the end of each chapter the mathematical and historical context of the material is given

Iterative Krylov Methods for Large Linear Systems

Series: Cambridge Monographs on Applied and Computational Mathematics (No. 13)
Paperback (ISBN-13: 9780521183703)

Computational simulation of scientific phenomena and engineering problems often depends on solving linear systems with a large number of unknowns. This book gives insight into the construction of iterative methods for the solution of such systems and helps the reader to select the best solver for a given class of problems. The emphasis is on the main ideas and how they have led to efficient solvers such as CG, GMRES, and BI-CGSTAB. The author also explains the main concepts behind the construction of preconditioners. The reader is encouraged to gain experience by analysing numerous examples that illustrate how best to exploit the methods. The book also hints at many open problems and as such it will appeal to established researchers. There are many exercises that motivate the material and help students to understand the essential steps in the analysis and construction of algorithms.

* Now in paperback, it incorporates corrections from the author * Based on extensive teaching experience * Contains numerous exercises and references for further reading

Topology for Computing

Series: Cambridge Monographs on Applied and Computational Mathematics (No. 16)
Paperback (ISBN-13: 9780521136099)

The emerging field of computational topology utilizes theory from topology and the power of computing to solve problems in diverse fields. Recent applications include computer graphics, computer-aided design (CAD), and structural biology, all of which involve understanding the intrinsic shape of some real or abstract space. A primary goal of this book is to present basic concepts from topology and Morse theory to enable a non-specialist to grasp and participate in current research in computational topology. The author gives a self-contained presentation of the mathematical concepts from a computer scientistfs point of view, combining point set topology, algebraic topology, group theory, differential manifolds, and Morse theory. He also presents some recent advances in the area, including topological persistence and hierarchical Morse complexes. Throughout, the focus is on computational challenges and on presenting algorithms and data structures when appropriate.

* Presents classical topological subject of Morse theory in a computer science context * Material is widely used within computation geometry and computer graphics
