Extremely amenable groups and the Ramsey property (I)

Logic Seminar

Meeting Details

For more information about this meeting, contact Kristin Berrigan, Jan Reimann, Linda Westrick.

Speaker: Jan Reimann, Penn State

Abstract: This is the first of two talks in which I will prove that the extremely amenable closed subgroups of the countable symmetric group are precisely the automorphism groups of Fraissé limits of Fraissé order classes with the Ramsey property. This result is due to Kechris, Pestov, and Todorcevic (2005). Zoom link: https://psu.zoom.us/j/529094287
