Finite Packing and Covering

Publication is planned for Oct. 2003 | Hardback | 240 pages | ISBN: 0-521-80157-5

Cambridge Tracts in Mathematics vol.154

Finite arrangements of convex bodies were intensively investigated in the second half of the 20th century. Connections to many other subjects were made, including crystallography, the local theory of Banach spaces, and combinatorial optimisation. This book, the first one dedicated solely to the subject, provides an in-depth state-of-the-art discussion of the theory of finite packings and coverings by convex bodies. It contains various new results and arguments, besides collecting those scattered around in the literature, and provides a comprehensive treatment of problems whose interplay was not clearly understood before. In order to make the material more accessible, each chapter is essentially independent, and two-dimensional and higher-dimensional arrangements are discussed separately. Arrangements of congruent convex bodies in Euclidean space are discussed, and the density of finite packing and covering by balls in Euclidean, spherical and hyperbolic spaces is considered.

Hydrodynamic Stability, 2nd Edition

Publication is planned for November 2003 | Paperback | 600 pages 102 line diagrams 3 half-tones 9 tables 81 exercises | ISBN: 0-521-52541-1

Hydrodynamic stability is of fundamental importance in fluid mechanics and is concerned with the problem of transition from laminar to turbulent flow. Drazin and Reid emphasise throughout the ideas involved, the physical mechanisms, the methods used, and the results obtained, and, wherever possible, relate the theory to both experimental and numerical results. A distinctive feature of the book is the large number of problems it contains. These problems not only provide exercises for students but also provide many additional results in a concise form. This new edition of this celebrated introduction differs principally by the inclusion of detailed solutions for those exercises, and by the addition of a Foreword by Professor J. W. Miles.

Advanced Dynamics

November 2003 | Hardback | 434 pages 115 exercises 168 figures | ISBN: 0-521-82612-8

Advanced Dynamics is a broad and detailed description of the analytical tools of dynamics as used in mechanical and aerospace engineering. The strengths and weaknesses of various approaches are discussed, and particular emphasis is placed on learning through problem solving. The book begins with a thorough review of vectorial dynamics and goes on to cover Lagrangefs and Hamiltonfs equations as well as less familiar topics such as impulse response, and differential forms and integrability. Techniques are described that provide a considerable improvement in computational efficiency over the standard classical methods, especially when applied to complex dynamical systems. The treatment of numerical analysis includes discussions of numerical stability and constraint stabilization. Many worked examples and homework problems are provided. The book is intended for use on graduate courses on dynamics, and will also appeal to researchers in mechanical and aerospace engineering.

Contents

1. Introduction to particle dynamics; 2. Lagrangefs and Hamiltonfs equations; 3. Kinematics and dynamics of a rigid body; 4. Equations of motion: differential approach; 5. Equations of motion: integral approach; 6. Introduction to numerical methods; Appendix.

Association Schemes
Designed Experiments, Algebra and Combinatorics

November 2003 | Hardback | 390 pages 100 line diagrams | ISBN: 0-521-82446-X

Association schemes are of interest to both mathematicians and statisticians and this book is written with both audiences in mind. For statisticians, it shows how to construct designs for experiments in blocks, how to compare such designs, and how to analyse data from them. The reader is only assumed to know very basic abstract algebra. For pure mathematicians, it tells why association schemes are important and develops the theory to the level of some recent research. This book has arisen from a course successfully taught by the author and as such the material is thoroughly class-tested. There are a great number of examples and exercises that will increase the bookfs appeal to both graduate students and their instructors. It is ideal for those coming either from pure mathematics or statistics backgrounds who wish to bring their understanding of association schemes up to the current state of the art.
