SUMMARY:Weimin Chen: \"Group actions on homotopy K3s\"
DESCRIPTION:Abstract: K3 surface is known to have the \"largest\" number
  of exotic smooth structures (K3 with an exotic smooth structure is call
 ed a homotopy K3). In this talk we will discuss several recent results (
 joint with S. Kwasik) about finite group actions on homotopy K3s which r
 eflect the following intuitive principle: exotic smooth structures are l
 ess symmetric.
