DESCRIPTION:Title: Quantizations of coadjoint orbit closures in positive 
 characteristics\n\nAbstract: If g = Lie(G) is the Lie algebra of an alge
 braic group over a field of characteristic zero then the closures of coa
 djoint orbits are Poisson varieties and it is natural and interesting to
  study their quantizations. Losev showed that when G is simple the quant
 izations are controlled by the one dimensional representations of a fini
 te W-algebra. In my 2021 paper with Premet we conjectured that "the same
 " should hold over fields of positive characteristics\, although here it
  is possible to state the conjecture without referencing W-algebras. In 
 this talk I will explain the results of a recent joint work with Ambrosi
 o and Westway in which we classify the quantizations of nilpotent coadjo
 int orbit closures for G = GL_N over a field of any positive characteris
 tic. I will try to keep it as non-technical as possible and focus on the
  intuition behind the methodology.
