Title of talk: Projective Modules over Frobenius Kernels
and Finite Chevalley Groups
Abstract: Let $G$ be a reductive algebraic group scheme over
a field of characteristic $p0$ (e.g. $G=\text{GL}_{n}$), and $M$ is a finite-dimensional
$G$-module. One can differentiate this action to consider $M$ as a module for
${\mathfrak g}$ the Lie algebra of $G$. On the other hand one can restrict the
action to the finite subgroup $G({\mathbb F}_{p})$ (e.g. $\text{GL}_{n}({\mathbb
F}_{p})$ where ${\mathbb F}_{p}$ is the finite field of $p$ elements). In 1987,
Parshall conjectured that under these assumptions, if $M$ a projective ${\mathfrak
g}$-module then $M$ is a projective $G({\mathbb F}_{p})$-module. This conjecture
has a natural generalization for higher Frobenius kernels $G_r$ and finite Chevalley
groups $G({\mathbb F}_{q})$ where $q=p^{r}$. In this talk, I will present recent
results with Zongzhu Lin on a solution to this general conjecture and its applications
towards relating the representation/cohomology theory of Frobenius kernels and
finite Chevalley groups.

Colloquium
3:30pm, Room 304
Speaker: David Sinnou, University of Paris 6
Title of talk: Transcendental numbers and diophantine geometry.
Abstract: Starting with a few historical problems on transcendal
numbers, we shall explain how the tools developed for transcendental number
theory can now be used to tackle modern problems of arithmetic geometry.
Analysis
3:30pm, Room 222
Speaker: Shuzhou Wang, University of Georgia
Title of talk: Introduction to quantum permutation
group
Abstract: The quantum permutation group of the space of n point
is the quantum automorphism group of the space. Unlike the classical situation
of the permutation group, the algebra for the quantum permutation group of the
n point space is infinite dimensional if n is at least 4, and the fusion/decomposition
rules for its irreducible representations are the same as those for the Lie
group SO(3) for different n, and it is simple as a quantum group. Study of quantum
subgroups of the quantum permutation group such as the quantum automorphism
groups of finite graphs and leads to new compact quantum groups.
Though there is a rather large literature on the quantum permutation group, there are still many fundamental questions. For instance, how to construct the models of its irreducible representations? How to classify its simple quantum subgroups? etc.
I will try to make this series of talks as self-contained as possible, starting
from basic notions in the theory of compact quantum groups, and explain some
of the main results and main problems on the quantum permutation group.
