On braid groups and right-angled Artin groups

Francis Connolly and Margaret Doig

Abstract: In this article we prove a special case of a conjecture of A. Abrams and R. Ghrist about fundamental groups of certain aspherical spaces. Specifically, we show that the n-point braid group of a linear tree is a right-angled Artin group for each n.
