Stable Functions and Common Stabilizations of Heegaard Splittings
نویسنده
چکیده
We present a new proof of Reidemeister and Singer’s Theorem that any two Heegaard splittings of the same 3-manifold have a common stabilization. The proof leads to an upper bound on the minimal genus of a common stabilization in terms of the number of negative slope inflection points and type-two cusps in a Rubinstein-Scharlemann graphic for the two splittings.

Stabilization of Heegaard Splittings
For each g ≥ 2 there is a 3-manifold with two genus g Heegaard splittings that require g stabilizations to become equivalent. Previously known examples required at most one stabilization. Control of families of Heegaard surfaces is obtained through a deformation to
متن کاملFlipping and Stabilizing Heegaard Splittings
We show that the number of stabilizations needed to interchange the handlebodies of a Heegaard splitting of a closed 3manifold by an isotopy is bounded below by the smaller of twice its genus or half its Hempel distance. This is a combinatorial version of a proof by Hass, Thompson and Thurston of a similar theorem, but with an explicit bound in terms of distance. We also show that in a 3-manifo...
متن کاملHeegaard Surfaces and Measured Laminations, Ii: Non-haken 3-manifolds
A famous example of Casson and Gordon shows that a Haken 3-manifold can have an infinite family of irreducible Heegaard splittings with different genera. In this paper, we prove that a closed non-Haken 3-manifold has only finitely many irreducible Heegaard splittings, up to isotopy. This is much stronger than the Walderhausen conjecture. Another immediate corollary is that for any irreducible n...
متن کاملStabilizations of Heegaard Splittings of Sufficiently Complicated 3-manifolds (preliminary Report)
We construct several families of manifolds that have pairs of genus g Heegaard splittings that must be stabilized roughly g times to become equivalent. We also show that when two unstabilized, boundary-unstabilized Heegaard splittings are amalgamated by a “sufficiently complicated” map, the resulting splitting is unstabilized. As a corollary, we produce a manifold that has distance one Heegaard...
متن کاملincompressible surfaces and stabilizations of Heegaard splittings
We describe probably the simplest 3-manifold which contains closed separating incompressible surfaces of arbitrarily large genus. Two applications of this observation are given. (1) For any closed, orientable 3-manifold M and any integer m> 0, a surgery on a link inM of at most 2m+1 components will provide a closed, orientable, irreducible 3-manifold containing m disjoint, non-parallel, separat...
