Reflection Groups and Coxeter Groups – James E. Humphreys – Google Books

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. Assuming that the reader has a good knowledge of algebra, this concrete and up-to-date introduction to the theory of Coxeter groups is otherwise self contained, making it suitable for self-study as well as reflecyion.

Be the first to ask a question about Reflection Groups and Coxeter Group. In common with all of Humphrey’s books, it is written in a clear and helpful expository style, and so froups an excellent introduction to the subject.

The second part which is logically independent of, but motivated by, the first develops from scratch the properties of Coxeter groups in gruops, including the Bruhat ordering and the seminal work of Kazhdan and Lusztig on representations of Hecke algebras associated with Coxeter groups is introduced. Polynomial invariants of finite reflection groups; 4.
