Abstract

Given a finitely presented group QQ and a compact special cube complex XX with non-elementary hyperbolic fundamental group, we produce a non-elementary, torsion-free, cocompactly cubulated hyperbolic group Γ\Gamma that surjects onto QQ, with kernel isomorphic to a quotient of G=π1XG=\pi_1 X and such that max{cd(G),2}cd(Γ)cd(G)1max\{cd(G),2\}\geq cd(\Gamma)\geq cd(G)-1.
