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.
