Global rigidity of actions by higher-rank groups May 16 to May 20, 2022 American Institute of Mathematics, San Jose, CA Organizers: Aaron Brown, David Fisher, Ralf Spatzier, and Zhiren Wang Description: This workshop, sponsored by AIM and the NSF, will be devoted to actions of higher rank groups. The general theme is the global rigidity or classification of such actions (at times satisfying additional dynamical hypotheses) up to smooth changes of coordinates. Deadline: January 8, 2022 Details: http://aimath.org/workshops/upcoming/rigidhigherrank
