DESCRIPTION:Emily Norton\, Kaiserslautern\nGroups\, Arithmetic and Algebra
 ic Geometry Seminar\nAbstract: Level 2 Fock spaces may be categorified by 
 two different representation theoretic categories (which extend the catego
 rification by the Hecke algebra to the whole Fock space) -- categories O o
 f type B rational Cherednik algebras\, and categories of unipotent represe
 ntations of finite classical groups whose BN pair has a type B Weyl group.
  I will discuss the combinatorics of the branching rule for Harish-Chandra
  induction in terms of two crystals on the Fock space\, as well as an inte
 resting involution on charged bipartitions (generalizing the Mullineux inv
 olution) that is an isomorphism of the crystals.\nThis talk is based on jo
 int work with Thomas Gerber\, Nicolas Jacon\, plus one solo paper of the a
 uthor.
