Topic: 

Regularity of groups acting on the circle

Description: 

There is a rich interplay between the degree of regularity of a group action on the circle and the allowable algebraic structure of the group. I will outline some highlights of this theory, culminating in a construction due to Kim and myself of groups of every possible critical regularity $\alpha \in [1,\infty)$.
