GEOMETRY AND TOPOLOGY SEMINAR - I P M
SPEAKER:
Pooya Vahidi Ferdowsi (Caltech)
TITLE:
Proximal Actions, Strong Amenability, and Infinite Conjugacy Class Property
DESCRIPTION:
A continuous action of a countable discrete group on a Hausdorff compact space X is called proximal if for any pair of points x, y in X, we can simultaneously push them together, i.e. there exists a sequence of group elements g_n with lim g_n x = lim g_n y. A group is called Strongly Amenable if each of its proximal actions has a fixed point. Glasner introduced these notions and showed Strongly Amenable groups are Amenable. Moreover, he showed that virtually nilpotent groups are Strongly Amenable. In this talk I will present a recent result classifying strongly amenable groups. This is a joint work with Joshua Frisch and Omer Tamuz.
DATE & TIME:
Sunday, March 3, 2019, 10:00 - 12:00 (Exceptional time)
VENUE:
Lecture Hall 2, Niavaran Bldg.
