General (Main) Seminar MSRI program on DDC-Recovering algebraic curves from L-functions

Friday, 11/6/2020, 5:00pm - 11:59pm

Organizer: V. Harizanov and A. Shlapentokh

Friday, November 6, 12:00-1:00 ET on Zoom

Felipe Voloch, University of Canterbury, New Zealand

Title: Recovering algebraic curves from L-functions

Abstract: We discuss how to recover an algebraic curve over a finite field from L-functions associated with it. We look at the problem from a number of different angles, including the input coming from model theory, and pose some open questions. Joint work with J. Booher.

Dynamics Seminar-Almost Anosov flows and the tilings they generate

Friday, 10/23/2020, 6:00pm - 11:59pm

Friday, October 23,  2pm to 3 pm on Zoom

Title: Almost Anosov flows and the tilings they generate

Speaker: Robbie Robinson, GWU

Abstract: The suspension of the Baker transformations constructed last week gives what we call an “almost Anosov” flow. One can also flow along the unstable direction from any point. The result is a "tiling flow" shares many properties with horocycle flows. There are striking tilings of the hyperbolic plane that simultaneously code both the tiling flows and the almost Anosov flows, and graphically depict the Markov partition.
