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

31 Aug 2017  ·  Beeker Benjamin, Lazarovich Nir ·

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...
