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.
