This graduate textbook presents a concrete and up-to-date introduction to the theory of coxeter groups.
Check out the top books of the year on our page best books of 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.
Any coxeter group can be realized as a group generated by reflection on a certain contractible cell complex, and this complex is the principal subject of this book. The book explains a theorem of moussong that demonstrates that a polyhedral metric on this cell complex is nonpositively curved, meaning that coxeter groups are cat(0) groups.
20 jul 2014 a classification of irreducible coxeter groups, give a linear representation for an coxeter groups are synonymous with reflection groups.
This chapter is of an auxiliary nature and contains the modicum of the theory of finite reflection groups and coxeter groups which we need for a systematic.
In this paper we give a survey of the theory of coxeter groups and reflection groups. This survey will give an undergraduate reader a full picture of coxeter group theory, and will lean slightly heavily on the side of showing examples, although the course of discussion will be based on theory. We'll begin in chapter 1 with a discussion of its origins and basic examples.
The geometry and topology of coxeter groups is a comprehensive and authoritative treatment of coxeter groups from the viewpoint of geometric group theory. Groups generated by reflections are ubiquitous in mathematics, and there are classical examples of reflection groups in spherical, euclidean, and hyperbolic geometry.
This graduate textbook presents a concrete and up-to-date introduction to the theory of coxeter groups. The book is self-contained, making it suitable either for courses and seminars or for self-study. 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.
Indeed, real reflection groups are often called finite coxeter groups. The theory of complex reflection groups followed in 1954 with the shepherd-todd theorem.
In this graduate textbook professor humphreys presents a concrete and up-to- date introduction to the theory of coxeter groups.
We show that the centralizer of a reflection in a coxeter group.
Chapter 3 discusses the polynomial invariants of finite reflection groups, and the first part ends with a description of the affine weyl groups and the way they arise in lie theory. The second part (which is logically independent of, but motivated by, the first) starts by developing the properties of the coxeter groups.
Reflection groups also include weyl groups and crystallographic coxeter groups.
This chapter is of an auxiliary nature and contains the modicum of the theory of finite reflection groups and coxeter groups which we need for a systematic development of the theory of coxeter.
Finally, we show a number of coxeter groups are reflection rigid once twisting is taken into account.
Coxeter showed that a group γ is a finite reflection group of an euclidean space if and only if γ is a finite coxeter group.
$\begingroup$ even if i know a presentation for the group with the generating set of all reflections, it's still not obvious to me how i would decide if some subset of these form the simple generators for a coxeter group presentation.
A *reflection group* w is a finite group generated by reflections in gl(v).
This chapter is of an auxiliary nature and contains the modicum of the theory of finite reflection groups and coxeter groups which we need for a systematic development of the theory of coxeter matroids. A reflection group w is a finite subgroup of the orthogonal group of ℝ n generated by some reflections in hyperplanes (mirrors or walls).
Coxeter group, alternating group, presentation, length, poincaré series. Subgroup w is a (non-parabolic) reflection subgroup of w, carrying its own coxeter.
The group generated by reflection in these two lines is an infinite dihedral group, and the restriction of its action to the unit circle has dense orbits in the circle. This is not a coxeter group in the classical sense of a discrete reflection group.
Let w be a finite reflection group acting on a n-dimensional real vector space. V then w two famous poincaré series formulae for coxeter groups.

Cambridge core - geometry and topology - reflection groups and coxeter groups.
In any case, what we do is hard to motivate strictly in terms of coxeter groups. 3 follows couillens [1] (expanding bourbaki [1], iv, §2, exercise 23), but the remainder of the chapter is drawn almost entirely from kazhdan–lusztig [1], with added references to work influenced by theirs.
Reflection groups and coxeter groups in this graduate textbook professor humphreys presents a concrete and up-to-date introduction to the theory of coxeter.
In the next chapter these groups are classified by coxeter diagrams, and actual realizations of these groups are discussed. Chapter 3 discusses the polynomial invariants of finite reflection groups, and the first part ends with a description of the affine weyl groups and the way they arise in lie theory.
