One-relator groups with torsion are conjugacy separable

, 2013
We prove that one-relator groups with torsion are hereditarily conjugacy separable. Our argument is based on a combination of recent results of Dani Wise and the first author.

Embeddings of right-angled Artin groups

, 2010
We explicitly construct an embedding of a right-angled Artin group into a classical pure braid group. Using this we obtain a number of corollaries describing embeddings of arbitrary Artin groups into right-angled Artin groups and ...

The homotopy type of toric 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 build a CW-complex S homotopy equivalent to the arrangement complement ℜ x, with a combinatorial ...

REPRESENTATIONS OF BRAID GROUPS AND GENERALISATIONS [PDF]

, 2007
Few misprints corrected, simpler proof for proposition 10We define and study extensions of Artin's representation and braid monodromy representation to the case of topological and algebraical generalisations of braid groups.

Braid groups, orderings, and algorithms

, 1999
We define a natural and readily calculated bi-invariant strict total ordering of the n-strand pure braid group Pn. It is defined algebraically, using the Artin decomposition of Pn as a semi-direct product of free groups, together with a specific ...

Collision-free motions of round robots on metric graphs [PDF]

, 2013
In this thesis, we study the path-connectivity problem of configuration spaces of two robots that move without collisions on a connected metric graph. The robots are modelled as metric balls of positive radii.

Artin groups and local indicability

, 2002
This thesis consists of two parts. The first part (chapters 1 and 2) consists of an introduction to theory of Coxeter groups and Artin groups. This material, for the most part, has been known for over thirty years, however, we do mention some recent ...
