| Jul 24, 2013 at 5:59 | comment | added | Don Shanil | (continued) As you suggest another way of asking the question is 'what are the combinatorial conditions needed to get a special Ford spine?' | |
| Jul 24, 2013 at 5:32 | comment | added | Don Shanil | Yes, I want the faces to be hyperbolic polygons glued isometrically together along the edges. So I guess I am looking at is a decomposition of a 2-sphere with hyperbolic polygons glued together by isometries. Each vertex is either trivalent or quadrivalent. To give a bit more detail -- the special spine is actually obtained by decomposing the Haken manifold along a hierarchy such as that used by Waldhausen and Johannson. | |
| Jul 23, 2013 at 13:58 | comment | added | Ian Agol | Maybe you could define what you mean by "hyperbolic polyhedron"? Presumably you want the faces to be hyperbolic polygons, glued isometrically along the edges (this is satisfied e.g. by the Ford domain special spine). But what condition do you want for the angles at each vertex? | |
