Measure equivalence classification of right-angled Artin groups: the finite $\mathrm{Out}$ classes
Given a right-angled Artin group $G$ with finite outer automorphism group, we determine which right-angled Artin groups are measure equivalent (or orbit equivalent) to $G$

Braid pictures for Artin groups
, 1998 We dene the braid groups of a two-dimensional orbifold and introduce conventions for drawing braid pictures. We use these to realize the Artin groups associated to the spherical Coxeter diagrams an , bn = cn and dn and the aÆne diagrams An , Bn , Cn and

Right-angled Artin groups as finite-index subgroups of their outer automorphism groups
, 2022 We prove that every right-angled Artin group occurs as a finite-index subgroup of the outer automorphism group of another right-angled Artin group. We furthermore show that the latter group can be chosen in such a way that the quotient is isomorphic to $(

Algorithms in Braid Groups [PDF]
, 2003 Braid Groups have recently been considered for use in Public-Key Cryptographic Systems. The most notable of these system has been the Birman-Ko-Lee system presented at Crypto 2000.

Examples of centralizers in the Artin braid groups
, 2003 The goal of this paper is to construct examples of centralizers in the Artin braid groups requiring the number of generators quadratic in the number of strings. These examples disprove a recent conjecture of N. Franco and J. Gonzalez-Meneses.

The integer cohomology of toric Weyl arrangements [PDF]
A toric arrangement is a finite set of hypersurfaces in a complex torus, every hypersurface being the kernel of a character. In the present paper we prove that if T(W) is the toric arrangement defined by the cocharacters lattice of a Weyl group W, then ...

Artin's Braid Groups, Free Groups, And The Loop Space Of The 2-Sphere
, 2005 The purpose of this article is to describe connections between the loop space of the 2-sphere, and Artin's braid groups. The current article exploits Lie algebras associated to Vassiliev invariants in work of T.
