Veering triangulations and pseudo-Anosov flows

Princeton University Mathematics Department Colloquium
Topic:Veering triangulations and pseudo-Anosov flows
Speaker:Ian Agol
Affiliation:University of California, Berkeley; Distinguished Visiting Professor, School of Mathematics
Date:Wednesday, December 2
Time/Room:4:30pm - 5:30pm/Fine 314, Princeton University

We'll discuss veering triangulations associated to pseudo-Anosov mapping tori, and how they arise dynamically. We'll survey some of the results obtained regarding these triangulations. Then we’ll discuss a new construction of these triangulations associated to certain pseudo-Anosov flows, which is joint work with François Guéritaud.
