DESCRIPTION:I will describe an action of a quantized Heisenberg algebra on
  the (derived) categories of coherent sheaves on Hilbert schemes of ALE sp
 aces (crepant resolutions of C^2/G). This action essentially lifts the act
 ions of Nakajima and Grojnowski on the cohomology of these spaces. (joint 
 with Tony Licata)\n
