Cycling amenable groups and soficity
4:00PM, Wed Oct 18 2017, Math 250
I will give introduction to sofic groups and discuss a possible strategy towards finding a non-sofic group. I will show that if the Higman group were sofic, there would be a map from Z/pZ to itself, locally like an exponential map, satisfying a rather strong recurrence property. The approach to (non)-soficity is based on the study of sofic representations of amenable subgroups of a sofic group. This is joint work with Harald Helfgott.

Equivariant algebraic oriented cohomology and their applications
4:00PM, Mon Oct 23 2017, Math 250
We give an overview on recent developments in the study of algebraic oriented theories and their equivariant analogues (e.g. various K-theories, algebraic cobordism). We discuss various connections and applications to generalized Schubert calculus. This is based on several joint projects with B. Calmes and C. Zhong.
