Set Theory and Topological Algebra

Colloquium presented by Michael Hrusak (Universidad Nacional Autónoma de México-Morelia)

We shall discuss some recent applications of set-theoretic and model-theoretic methods to the study of topological groups. In particular, we shall outline how ultra powers can be used to solve old problems of Comfort and van Douwen and introduce a new set-theoretic axiom to study convergence properties in topological groups. If time permits we may also briefly mention the use of Fraissé theory in the study of groups of homeomorphisms.
