Length functions of 2-dimensional right-angled Artin groups (1103.5328v2)
Published 28 Mar 2011 in math.GR
Abstract: Morgan and Culler proved that a minimal action of a free group on a tree is determined by its translation length function. We prove an analogue of this theorem for 2-dimensional right-angled Artin groups acting on CAT(0) rectangle complexes.
