Combinatorial Dehn surgery on cubed and Haken 3–manifolds
Combinatorial Dehn surgery on cubed and Haken 3–manifolds
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 …
