In this paper we study hyperbolic groups acting on CAT(0) cube complexes. The
first main result (Theorem A) is a structural result about the Sageev
construction, in which we relate quasi-convexity of hyperplane stabilizers with
quasi-convexity of cell stabilizers. The second main result (Theorem D)
generalizes both Agol's theorem on cubulated hyperbolic groups and Wise's
Quasi-convex Hierarchy Theorem.Comment: 52pp. In v3, some unnecessary assumptions are dropped from some
technical results, especially in Section 5 and Corollary 6.5. The main
results are unchanged, but the improved technical results are expected to be
useful in future work. Several other small improvements to the exposition
have been mad
