Action dimensions of some simple complexes of groups

arXiv:1803.04095 · doi:10.1112/topo.12115

Abstract

The action dimension of a discrete group is the minimum dimension of contractible manifold that admits a proper -action. We compute the action dimension of the direct limit of a simple complex of groups for several classes of examples including: 1) Artin groups, 2) graph products of groups, and 3) fundamental groups of aspherical complements of arrangements of affine hyperplanes.
