K(π, 1)’s for Artin Groups of Finite Type Thomas Brady and Colum Watt

چکیده
In [4] a complex is constructed whose top-dimensional cells correspond to minimal factorizations of a Coxeter element as a product of reflections in a finite Coxeter group. Asphericity is established in low dimensions using a metric of non-positive curvature. Since the nonpositive curvature condition is difficult to check in higher dimensions a combinatorial approach is used in [3] in the case of the braid groups.

Lattices in Finite Real Reflection Groups Thomas Brady and Colum Watt
For a finite real reflection group W with Coxeter element γ we give a uniform proof that the closed interval, [I, γ] forms a lattice in the partial order on W induced by reflection length. The proof involves the construction of a simplicial complex which can be embedded in the type W simplicial generalised associahedron.
متن کاملClimbing Elements in Finite Coxeter Groups
We define the notion of a climbing element in a finite real reflection group relative to a total order on the reflection set and we characterise these elements in the case where the total order arises from a bipartite Coxeter element.
متن کاملConnectivity at Infinity for Right Angled Artin Groups
We establish sufficient conditions implying semistability and connectivity at infinity properties for CAT(0) cubical complexes. We use this, along with the geometry of cubical K(π, 1)’s to give a complete description of the higher connectivity at infinity properties of right angled Artin groups. Among other things, this determines which right angled Artin groups are duality groups. Applications...
متن کاملBestvina’s Normal Form Complex and the Homology of Garside Groups
A Garside group is a group admitting a finite lattice generating set D. Using techniques developed by Bestvina for Artin groups of finite type, we construct K(π, 1)s for Garside groups. This construction shows that the (co)homology of any Garside group G is easily computed given the lattice D, and there is a simple sufficient condition that implies G is a duality group. The universal covers of ...
متن کاملThree-generator Artin Groups of Large Type Are Biautomatic
In this article we construct a piecewise Euclidean, non-positively curved 2-complex for the 3-generator Artin groups of large type. As a consequence we show that these groups are biautomatic. A slight modification of the proof shows that many other Artin groups are also biautomatic. The general question (whether all Artin groups are biautomatic) remains open.
