DESCRIPTION:Title: Quantizations of nilpotent orbits in positive characte
 ristic\n\nAbstract: Nilpotent coadjoint orbits in a reductive Lie algebr
 a play an important role in the representation theory of Lie algebras\, 
 especially over fields of positive characteristic. One definition of a n
 ilpotent orbit is an orbit which is preserved by non-zero scalar multipl
 ication\; thus\, the coordinate rings of such orbits are graded algebras
 \, in fact graded Poisson algebras. For a graded Poisson algebra A\, a n
 atural problem is to classify the quantizations of A - filtered algebras
  whose associated graded algebra coincides with A. In this talk\, we con
 sider this problem for the general linear group and give a combinatorial
  classification of (Hamiltonian) quantizations in this case. This is joi
 nt work with Filippo Ambrosio and Lewis Topley.
