3-Manifold Seminar: Guts components of sutured decomposition and the Thurston Norm

Seminar | December 5 | 11:10 a.m.-12:30 p.m. | 939 Evans Hall

In this talk, I will try to give an introduction of Thurston norm, sutured decomposition. Furthermore we define the guts components of a homology class as the nontrivial parts in a sutured decomposition of the 3-manifold. I will show a statement that the guts do not depend on the selection of the facet surfaces and some examples in 3-manifolds which should satisfy our results. This is based on joint work with Ian Agol.
