Gizem added it Jun 20, There are a bunch of things I have been vaguely hearing about for a long time and I grops 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: At the same time the material dealing with recent developments such as Kazhdan-Lusztig theory will be most useful to specialists in the area.

Chapter 8, which geflection like an “introduction to the broader literature” chapter, with a bunch of miscellaneous cool topics and no proofs, was nice, but I think I hupmhreys have been more excited reading a chapter like this that was written much more recently.

Every so often I would take out a notebook, but mostly I was just reading and thinking, so I could read it on train rides, before bed, etc. This book is not yet featured on Listopia.

Reflection Groups and Coxeter Group by James E. Humphreys

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.

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. Volume 1 Claire Voisin. Matthew rated it really liked it Jan 01, He assumes that the reader has a good knowledge of algebra, but otherwise the book is self contained. The math is just so gorgeous! Description This graduate textbook presents a concrete and up-to-date introduction to the theory of Coxeter groups.
