Mittagsseminar zur Arithmetik: Kestutis Cesnavicius (Paris): The affine Grassmannian as a presheaf quotient
Friday, 09.06.2023 10:15 im Raum SRZ 216/217
The affine Grassmannian of a reductive group G is usually defined as the étale 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.
