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 whole theory is just heavenly. Sean Elvidge rated it it was amazing Jan 18, At the same time the material dealing with recent developments such as Kazhdan-Lusztig theory will be most useful to specialists in the area.

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.

The first part is devoted to establishing concrete examples; the author Chapter 8, which is like an “introduction to the broader literature” chapter, with a bunch of miscellaneous cool topics and no proofs, was nice, but I think I would have been more excited reading a chapter like this that was written much more recently.

Aug 25, Mikhail Ignatev rated it really liked it Shelves: Refllection really enjoyed this book, especially chapters 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: In this graduate textbook Professor Humphreys presents a concrete and up-to-date introduction to the theory of Coxeter groups.
