Series: Penn State Logic Seminar Date: Tuesday, November 2, 2004 Time: 2:30 - 3:45 PM Place: 307 Boucke Building Speaker: John Clemens, Penn State, Mathematics 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.
