DESCRIPTION:TITLE \n\nDiffeomorphisms of discs (Conférence de Prix André Ai
 senstadt 2024).\n\nABSTRACT\n\nDiscs are among the simplest manifolds\, bu
 t 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 grou
 ps to stable homotopy theory and number theory in high dimensions\, and re
 cent breakthroughs in understanding their rational homotopy type. This tal
 k will be aimed at a broad audience.\n\nPLACE\n	Hybride - CRM\, Salle / Roo
