In common with all of Humphrey’s books, it is written in a clear and helpful expository style, and so gives an excellent introduction to the subject. Sean McAfee rated it it was amazing Mar 12, The second part coexter is logically independent of, but motivated by, the first develops from scratch the properties of Coxeter groups in general, including the Bruhat ordering and the seminal work of Kazhdan and Lusztig on representations of Humpherys algebras associated with Coxeter groups is introduced.

Because most of what was going on was so well-motivated and well-explained, and because the exercises were interspersed with the text and there were not very many — kind of just enough to let you check you know what is going on — this went pretty quickly and didn’t force me to devote more time to it than I had.
