Adriane Kaïchouh: Amenability and convex Ramsey theory
Donnerstag, 27.02.2014 10:30 im Raum M5
Moore recently characterized the amenability of automorphism groups of countable ultrahomogeneous structures by a Ramsey-type property (in the vein of the Kechris-Pestov-Todorcevic correspondence). We will present this property and give a generalization of Moore's result to automorphism groups of separable metric structures, which encompass all Polish groups. We will also discuss some nice consequences of this characterization."
