Universal Minimal Flows of Groups of Automorphisms of Uncountable Structures

Dynamical Systems 2011-11-22 v1

Abstract

It is a well-known fact, that the greatest ambit for a topological group GG is the Samuel compactification of GG with respect to the right uniformity on G.G. We apply the original destription by Samuel from 1948 to give a simple computation of the universal minimal flow for groups of automorphisms of uncountable structures using Fra\"iss\'e theory and Ramsey theory. This work generalizes some of the known results about countable structures.
