Witryna2 mar 2005 · Suppose M is a cusped finite-volume hyperbolic 3-manifold and $${\\mathcal{T}}$$ is an ideal triangulation of M with essential edges. We show that any incompressible surface S in M that is not a virtual fiber can be isotoped into spunnormal form in $${\\mathcal{T}}$$. The proof is based directly on ideas of W. Thurston. WitrynaLet F be a closed essential surface in a hyperbolic 3‐manifold M with a toroidal cusp N . The depth of F in N is the maximal distance from points of F in N to the boundary of N . It will be shown that if F is an essential pleated surface which is not coannular to the boundary torus of N then the depth of F in N is bounded above by a constant …
