Title: The definable subgroups of the fundamental group

Abstract: The fundamental group of a topological space can carry a great deal of information about the space.  Some recent advances in the study of fundamental groups, and especially the subgroups one can define using a combination of first-order logic and topology, will be presented.  Background definitions and illustrative examples will be provided, as well as some open questions.
