Hello everyone,

Henry will be speaking today in seminar. His title and abstract are below:

From veering triangulations to pseudo-Anosov flows

Speaker: Henry Segerman, OSU

Date: Nov 8, 2017

Time: 3:30 PM

Room: MSCS 509

Abstract: Agol introduced veering triangulations of mapping tori, whose combinatorics are canonically associated to the pseudo-Anosov monodromy. Guéritaud and Agol generalised an alternative construction to any closed manifold equipped with a pseudo-Anosov flow without perfect fits. We prove the converse, showing that veering triangulations are a perfect combinatorialisation of such flows.
