If is irreducible, then the eigenvalues of its Killing—Coxeter element see Coxeter group are equal towhere is the Coxeter number: The assertions of the previous paragraph, with the exception of the last, also apply to linear groups over an arbitrary field of characteristic zero see [4]. The math is just so gorgeous! The references compile nearly a hundred articles and books.

Description This graduate textbook presents a concrete and up-to-date introduction to the theory of Coxeter groups. 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.
