DESCRIPTION:We describe a higher dimensional analogue of the Stallings fol
 ding sequence for group actions on CAT(0) cube complexes. We use it to giv
 e a characterization of quasiconvex subgroups of hyperbolic groups which a
 ct properly co-compactly on CAT(0) cube complexes via finiteness propertie
 s of their hyperplane stabilizers. Joint work with Benjamin Beeker.<br>
