Locally unknotted spines of Heegaard splittings
نویسنده
چکیده
We show that under reasonable conditions, the spines of the handlebodies of a strongly irreducible Heegaard splitting will intersect a closed ball in a graph which is isotopic into the boundary of the ball. This is in some sense a generalization of the results by Scharlemann on how a strongly irreducible Heegaard splitting surface can intersect a ball. AMS Classification 57M27; 57Q10

Parity Condition for Irreducibility of Heegaard Splittings
Casson and Gordon gave the rectangle condition for strong irreducibility of Heegaard splittings [1]. We give a parity condition for irreducibility of Heegaard splittings of irreducible manifolds. As an application, we give examples of non-stabilized Heegaard splittings by doing a single Dehn twist.
متن کاملRectangle Condition for Irreducibility of Heegaard Splittings
Casson and Gordon gave the rectangle condition for strong irreducibility of Heegaard splittings [1]. We give a weak version of rectangle condition for irreducibility of Heegaard splittings. As an application, we give an example of an irreducible genus three Heegaard splitting of a 3-manifold which is not a minimal genus Heegaard splitting.
متن کامل1 8 Ja n 20 01 Heegaard splittings of exteriors of two bridge knots
By H.Goda, M.Scharlemann, and A.Thompson [6] (see also K.Morimoto’s paper [15]), or [13], it is shown that, for each non-trivial two bridge knot K, every genus two Heegaard splitting of E(K) is isotopic to either one of six typical Heegaard splittings (see Figure 7.1). We note that Y.Hagiwara [7] proved that genus three Heegaard splittings obtained by stabilizing the six Heegaard splittings are...
متن کاملNormal Surfaces
We define a 2-normal surface to be one which intersects every 3-simplex of a triangulated 3-manifold in normal triangles and quadrilaterals, with one or two exceptions. The possible exceptions are a pair of octagons, a pair of unknotted tubes, an octagon and a tube, or a 12-gon. In this paper we use the theory of critical surfaces developed in [Baca] to prove the existence of topologically inte...
