DESCRIPTION:Speakers: Drimik Roy Chowdhury (IMJ-PRG\, Sorbonne Université
 )\n\nWe introduce the notion of gerbes — a higher categorical analogue o
 f torsors. We discuss their many incarnations coming from various formalis
 ms (e.g.\, Azumaya algebras and Brauer groups\, Tannakian categories) and 
 then study in detail Nori’s fundamental group scheme and its generalizat
 ion as a gerbe.\n\nhttps://indico.math.cnrs.fr/event/16303/
