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.

Title:Fusion categories and their invariants
4:00PM, Mon Oct 30 2017, Math 250
The objects in fusion categories generalize complex
representations for finite groups. In particular, they are semisimple
tensor categories whose objects have duals. These categories arise
from the representation theory of a diverse range of objects, most
notably in Drinfel’d’s theory of quantum groups and Jones’s theory of
Murray-von Neumann factors. The problem of classifying fusion
categories whose tensor product has a given ring structure is the
central question of this talk. The answer to this question even for
rings that are very close to group algebras is very difficult. We
will survey the existing answers to this question; successful
approaches have highlighted the importance of tools brought over from
the theory of finite groups, including group cohomology and
Frobenius-Schur indicators.
