Klappentext zu „Reflection Groups and Invariant Theory “
Reflection Groups and their invariant theory provide the main themes of this book and the first two parts focus on these topics. The first 13 chapters deal with reflection groups (Coxeter groups and Weyl groups) in Euclidean Space while the next thirteen chapters study the invariant theory of pseudo-reflection groups. The third part of the book studies conjugacy classes of the elements in reflection and pseudo-reflection groups. The book has evolved from various graduate courses given by the author over the past 10 years. It is intended to be a graduate text, accessible to students with a basic background in algebra. Richard Kane is a professor of mathematics at the University of Western Ontario. His research interests are algebra and algebraic topology. Professor Kane is a former President of the Canadian Mathematical Society.

Autoren-Porträt von Richard Kane
Preliminary Text. Reflection groups and invarian theory is a branch of the intersection between geometry and algebra. It has a deep and elegant theory which is both of great interest in its own right and also related to other significant areas of mathematics. This book has evolved from various graduate courses given by the author over the past 10 years. It is intended to be a graduate text, accessible to students with a basic background in algebra.

From the reviews: CANADIAN MATHEMATICAL SOCIETY NOTES
"The former group are interested in Lie algebras and algebraic groups while the latter group includes commutative algebraists and topologists. This is the first book I've read that is aimed at both audiences, providing a clear exposition of a truly beautiful area of mathematics. It is probably fair to say there isn't much new in the book, except to find all the relevant material in the one place, well-organized and well-explained...This is a very lovely book to read. I found the pace of the book to be perfect. The approach follows the development of the subject in the literature closely - this is how it was discovered, more or less. It appears to my eye to be accessible to a first-year graduate student. It is not overly terse, nor overly wordy and there are many examples."
ZENTRALBLATT MATH
"The book is certainly a good source of information mainly in the more advanced areas of the subject. The references compile nearly a hundred articles and books."
MATHEMATICAL REVIEWS
"The book is a very accessible introduction to a wonderful part of mathematics that has many applications...it can be pointed out that the approach taken in this book includes examples of the use of Galois theory, Cohen Macaulay properties, Hopf algebras, representation theory and basic algebraic geometry. This is a nice way to see applications of these areas...The book would certainly be a good choice to teach the ideas in the above list, as the book flows very well. Each chapter is well motivated and summarized in its introduction."
"This book by the Canadian mathematician Richard Kane is an elementary exposition of the theory of finite pseudo-reflection groups ... . It can be read by a beginning graduate student, it requires almost no prerequisites and never becomes hard to read. ... it has a good list of references to the not too recent literature. ... All in all it is

acarefully written book that can be recommended to a graduate student for independent study, containing a good amount of interesting material." (A. Broer, Nieuw Archief voor Wiskunde, Vol. 6 (2), 2005)
"The main theme of this book is a study of the properties of reflection groups ... . The book is nicely organised and written in a very understandable way. The main ideas are clearly explained at the beginning of each chapter, so it is easy to learn the facts first and to fill in the details later, when needed. ... The book is pleasant to read, and can be heartily recommended to a general mathematical audience, starting with graduate students." (European Mathematical Society Newsletter, September, 2003)
"This graduate text develops the structure theory of finite reflection groups ... . It is worth mentioning that many useful diagrams and tables are included in the text ... . Some background information is provided at various places in the text and in appendices on rings and modules, group actions and representations, quadratic forms and Lie algebras. The book is easily readable and informative; thus it can be warmly recommended to every mathematician or mathematical physicist needing an introduction to reflection groups ... ."
