Keller 303
Speaker: James Hyde, Copenhagen
Title: Groups, Orders and Dynamics.
Abstract:  I will describe some of the history of combinatorial group theory, and its connections with algorithmic questions such as the decidability of the word problem.
I will then define ordered groups and describe their connection to group actions on the real line. Then I will state some of my recent results (in part joint with Lodha) resolving two central questions in the area.
