Stallings folds for CAT(0) cube complexes and quasiconvex subgroups

Published 9 May 2016 in math.GR | (1605.02758v2)

Abstract: We describe a higher dimensional analogue of the Stallings folding sequence for group actions on CAT(0) cube complexes. We use it to give a characterization of quasiconvex subgroups of hyperbolic groups which act properly co-compactly on CAT(0) cube complexes via finiteness properties of their hyperplane stabilizers.
