Jun 01,  · I really enjoyed this book, especially chapters 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/5(2).

We follow closely the terminology and notation of Humphreys [14]. of Coxeter groups (associated with the connected T-shaped Coxeter–Dynkin diagram). Coxeter group. However, not all Coxeter groups are finite, and not all can be described in terms of symmetries and Euclidean reflections. Coxeter groups were introduced (Coxeter ) as abstractions of reflection groups, and finite Coxeter groups were classified in (Coxeter ). In this graduate textbook Professor Humphreys presents a concrete and up-to-date introduction to the theory of Coxeter groups. He assumes that the reader has a good knowledge of algebra, but otherwise the book is self contained. The first part is devoted to establishing concrete examples; the author begins by developing the most important facts about finite reflection groups and related.

The dihedral group D m consists of m reflections and m rotations, which can be expressed as products of reflections. Example: Let the symmetric group S n act on R .

The Coxeter number is the order of any Coxeter element;. The Coxeter number is 2 m / n, where n is the rank, and m is the number of reflections. In the crystallographic case, m is half the number of roots; and 2m + n is the dimension of the corresponding semisimple Lie algebra.

In dimension n = 4 there are three additional regular polytopes, and all their symmetry groups are finite reflection groups [23], [4].
