Title: Ellis' problem for automorphism groups
Abstract: Ellis' problem is a problem from topological dynamics asking whether two well studied flows are canonically isomorphic. In the case of groups of automorphisms of discrete structures, we can translate this problem into a question about Boolean algebras and solve the problem for some countable structures. We also arrive at questions about existence of certain ultrafilters. This is a join work with Andy Zucker.
