At the same time the material dealing with recent developments such as Kazhdan-Lusztig theory will be most useful to specialists in the area. The first part is devoted to establishing concrete examples; the author begins by developing the most important facts about finite reflection groups and related geometry, and showing that such groups have a Coxeter representation.

The first part is devoted to establishing concrete examples; the author Review quote “This is a book which can be recommended to both beginners and more experienced workers with an interest in Coxeter groups.

Meanwhile there are a bunch of other totally beautiful things that I didn’t know at all: The anx theory is just heavenly.

The book is self-contained, making it suitable either for courses and seminars or for self-study. Popular passages Page Gizem added it Jun 20, Finally a number of interesting complementary topics as well as connections with Lie theory are sketched.

Andrew rated it liked it Jul 08, It certainly helped that I’ve actually done work with Coxeter groups and therefore I wasn’t learning from scratch, but this is the first time I’ve had the experience of reading a graduate math textbook essentially as bedside reading and having that really work out well.

The second part which is logically independent of, but motivated by, the first starts by developing the properties of the Coxeter groups.

Tao Kai added it Sep 19, Finite reflection groups acting on Euclidean spaces are discussed, and the first part ends with the construction of the affine Weyl groups, a class of Coxeter groups that plays a major role in Lie theory. Sep 08, Ben added it. Table of contents Part I. There are a bunch of things I have been vaguely hearing about for a long time and I knew the definition but it seemed kinda random and I didn’t understand how it was connected to anything, and which I now fully understand why people love them: Open Preview See a Problem?
