URegina-PIMS Distinguished Lecture: Alexander Kupers

  • Date: 10/28/2022
  • Time: 15:30
Lecturer(s):
Alexander Kupers, University of Toronto
Location: 

University of Regina

Topic: 

Diffeomorphisms of discs

Description: 

Discs are among the simplest manifolds, but their groups of diffeomorphisms can be very complicated. I will describe the techniques from geometry topology and dynamics that were used to understand these groups in low dimensions, the relationship of these groups to stable homotopy theory and number theory in high dimensions, and recent breakthroughs in understanding their rational homotopy type. This talk will be aimed at a broad audience.
