Title:Area preserving flows on surfaces: survey and new exceptional behaviour
Seminar:Center for Dynamics and Geometry Colloquium
Speaker:Alex Wright, Stanford University
Since the 60s, the ergodic behaviour of area preserving flows on surfaces has been extensively studied. We now know that such flows are typically uniquely ergodic and weak mixing, but typically not mixing. In the case of smooth flows on the torus, or straight line flows on translation surfaces, they are never mixing. We will give a brief survey of this story, and explain a new contribution: there exists a mixing smooth flow on a surface with non-degenerate fixed points. Joint work with Jon Chaika.
