DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MITNT/79/">T
 he affine Grassmannian as a presheaf quotient</a>\nby Kestutis Cesnavicius
  (Université Paris-Saclay) as part of MIT number theory seminar\n\nLectur
 e held in Room 2-449 in the Simons Building (building 2).\n\nAbstract\nThe
  affine Grassmannian of a reductive group $G$ is usually defined as the é
 tale sheafification of the quotient of the loop group $LG$ by the positive
  loop subgroup. I will discuss various triviality results for $G$-torsors 
 which imply that this sheafification is often not necessary.\n
