Title: Generating E_0

Abstract:

  The equivalence relation E_0 is defined on the Cantor space by
  setting two sequences equivalent if they differ on only finitely
  many coordinates. This relation plays a fundamental role in the
  study of hyperfinite equivalence relations. In this talk, I will
  discuss several questions concerning how this equivalence relation
  can be generated by "nice" group actions.
