Session 1: April 9-11, 2021 & Session 2: April 16-18, 2021
Beginning in Fall 1991, the dynamics groups of the University of Maryland and Pennsylvania State University have jointly sponsored two annual three to four day meetings in dynamical systems and related topics: a spring meeting here in College Park, and a fall meeting in State College. These meetings, though primarily regional, also attract participants outside the region and the country; the conference archives indicate their scope.
The 2021 Maryland Workshop on Dynamical Systems will take place over two weekends, April 9-11 (session 1) and April 16-18 (session 2). The first session will promarily be devoted to systems of zero entropy, whereas the second session will be devoted to hyperbolic systems.
The Michael Brin Prize talks will take place during the first session.
Recordings of the talks of the first day (Gorodnik, MacAdam, Edward) are here.
Recordings of the talks of the second day (Wang, Vinhage, Lemanczyk and Marmi (first half)) are here and here is the second half of Marmi's talk.
Recordings of the talks of the third day (Cortez, Sanadhya, Scheglov) are here.
Recordings of main lectures of day 4 (Bálint, Zelerowicz, Demers) are here. Török's talk is here.
Recordings of main lectures of day 5 (Bálint, Pène, Erchenko) are here. Hazoori's talk is here.
