Abstract: The theory of orderable groups is a very classical subject, which is enjoying a sort of revival, in part because of its connections with topology. This talk will give an overview of some of these connections, in particular the braid groups, knot groups, and fundamental groups of surfaces and 3-dimensional manifolds. I will touch on the relevance of orderability to issues such as group actions and foliations on manifolds. The talk should be accessible to anyone who knows the definition of a group.
