Combinatorial Dehn surgery on cubed and Haken 3-manifolds

IR Aitchison and JH Rubinstein

Abstract. A combinatorial condition is obtained for when immersed or embedded incompressible surfaces in compact 3--manifolds with tori boundary components remain incompressible after Dehn surgery. A combinatorial characterisation of hierarchies is described. A new proof is given of the topological rigidity theorem of Hass and Scott for 3--manifolds containing immersed incompressible surfaces, as found in cubings of non-positive curvature.
