SUMMARY:Pure Math Department Colloquium
CLASS:PUBLIC
DESCRIPTION:JON BRUNDAN\, UNIVERSITY OF OREGON\n\nClassical representation 
 theory via categorification\n\nThe standard approach to many sorts of repr
 esentation theory related\nto reductive algebraic groups and semisimple Li
 e algebras is based on\nthe combinatorics of the underlying Weyl group (an
 d its Hecke\nalgebra). In Cartan type A\, there is another approach exploi
 ting\ncombinatorics of an underlying Kac-Moody algebra (or its quantized\n
 enveloping algebra). This was developed in examples over many decades\,\na
 nd fits into a unified general framework which we now call\n`Heisenberg ca
 tegorification'. Analogous approaches are slowly\nemerging for the other f
 amilies of classical groups (and supergroups).\nI will explain the general
  setup and some of its consequences\, with\nexamples.\n\nMC 5501
