Representation Theory & Categorification
In modern representation theory we often study the category of
modules over an algebra, in particular its intrinsic and
combinatorial structures. Vice versa one can ask the question:
which categories have a given combinatorics? This is the
basic...
Representation Theory & Combinatorics of the Symmetric Group and Related Structures
Monica Vazirani
With an eye toward coordinating with the advanced course, we
will start with the representation theory of the symmetric group
and related combinatorics. We will focus on the functors of
induction and restriction. We will then consider related...
Three 20 minute research talks

Oğuz Şavk (Boğaziçi University),
Classical and new plumbings bounding contractible manifolds
and homology balls
A central problem in low-dimensional topology asks which
homology 3-spheres bound contractible 4-manifolds and homology
4-balls. In this...
Character estimates for classical finite simple groups
4:30pm|Simonyi Hall 101 and Remote Access
This is intended to complement the recent talk of Pham Huu Tiep
in this seminar but will not assume familiarity with that talk. The
estimates in the title are upper bounds of the form $|\chi(g)| \le
\chi(1)^\alpha$, where $\chi$ is irreducible and $...
Kazhdan-Lusztig equivalence
Continuation of the previous talk.

Chelsea Walton
Abstract: This is a tale about my adventures of being trained as
a Ring Theorist to now using Category Theory in my work. This is
something that I certainly did not predict when I defended my
thesis 10 years ago, but the best stories are...
Geometric Categorifications of the Hecke Algebra
Laura Rider
Abstract: In the first part of this talk, I'll explain a
geometric categorification of the Hecke algebra in terms of
perverse sheaves on the flag variety. In the second part, we'll
study the affine Hecke algebra. In this case, there are two...
