Lecturer(s):
Thomas Koberda, University of Virginia
Location:

University of British Columbia

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 $\alpha \in [1,\infty)$.
