Abstract

Braid group Configuration space Right-angled Artin group
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. © 2014, Springer Science+Business Media Dordrecht.
