Series: Penn State Logic Seminar Date: Tuesday, February 17, 2004 Time: 2:30 - 3:45 PM Place: 307 Boucke Building Speaker: John Clemens, Penn State, Mathematics Title: Isometry of Polish Metric Spaces, part 2 Abstract: I will continue discussing the classification problem of Polish metric spaces up to isometry. I will show that the orbit equivalent relation of an arbitrary Polish group action is reducible to this problem, and discuss some particular classes of metric spaces.
