DESCRIPTION:Paul Levy [Lancaster]\nThe geometry of nilpotent cones of simp
 le complex Lie algebras is in general highly complicated\, with deep conne
 ctions to representation theory\, primitive ideals of the universal envelo
 ping algebra and the theory of symplectic singularities. An ongoing joint 
 programme of research with Baohua Fu\, Daniel Juteau and Eric Sommers aims
  to better understand this geometry for exceptional Lie algebras\, especia
 lly by examining unions of closely related singular strata.\nThis talk wil
 l focus on the special nilpotent orbits\, or rather\, on their associated 
 special pieces. It was conjectured by Lusztig that every special piece is 
 the quotient of a smooth variety by a finite group. Here we will outline h
 ow direct calculations in transverse slices can be employed to establish a
  "(very) local version" of Lusztig's conjecture.
