Topological dynamics of automorphism group of countably categorical structures
E-mail:

Submission date: 20 December 2014.

Abstract:

We consider automorphism groups of some countably categorical structures and their precompact expansions. We prove that automorphism groups of omega-stable omega-categorical structures have metrizable universal minimal flows. We also study amenability of these groups. This is a draft of a paper which will be extended by some other results.
