University of Georgia VIGRE
Algebra Group
Our research group was initiated in August 2003 under the Vertical
Integration of Research and Education (VIGRE)
Program sponsored by the National Science Foundation (NSF) at the
Department of Mathematics at the University
of Georgia (UGA). The group was initially led from 2003-05
by David Benson, Brian Boe and Daniel Nakano.
The faculty leaders from 2005-08 were Brian Boe, Leonard Chastkofsky,
and Daniel Nakano. In 2009-10, the
group will be led by Brian Boe, Jon Carlson, Leonard Chastkofsky, and
Daniel Nakano.
The VIGRE Algebra Group consists of faculty members, postdoctoral
fellows, graduate students and undergraduates. Our group
operates much like a laboratory in the physical and biological sciences
by bringing individuals with varying backgrounds and expertise
to work on a common research project. One of our main educational
objectives has been to develop innovative methods for conducting
mathematical research in a large group atmosphere.
During the 2003-04 academic year we focused our efforts on
understanding conjugacy classes of nilpotent orbits
via the use of cohomology and representation theory. In 2004-05, our
group studied support varieties for modules
over the symmetric group. From 2005-08, we investigated methods
for computing cohomology for Lie algebras, quantum
groups and other related objects. Our group has completed five papers
including one software package:
- Varieties for Nilpotent Matrices over Simple Lie Algebras I:
Good Primes, J. Algebra 280, (2004), 719-737.
- Varieties for Nilpotent Matrices over Simple Lie Algebras II:
Bad Primes, J. Algebra 292, (2005), 65-99.
- Support Varieties for Weyl Modules over Bad Primes, J. Algebra
312, (2007), 602-633.
- On Kostant's Theorem for Lie Algebra Cohomology, Cont. Math. 478,
(2009), 39-60.
- Cohomology for quantum groups: An analog of Kostant's Theorem, to
appear in the Proceedings of the AMS
- GAP program UGA3 (gzipped tar or
zip format)
to
determine support varieties of induced modules for exceptional groups
over
bad primes.
- A minor correction to a table at the top of page 732 in the paper
"Varieties for
Nilpotent Matrices over Simple Lie Algebras I: Good Primes": Revised Table
The GAP program is a companion to the paper "Support varieties for Weyl
modules over bad primes."
GAP is available from http://www-gap.dcs.st-and.ac.uk/~gap/. Versions
are available for UNIX/Linux, Windows, or Macintosh OS.
This year 2009-10, we will investigate the cohomology of finite groups.
In particular we will focus our attention on computations of
low degree cohomology for symmetric groups and finite groups of Lie
type.

group setting can be found in our biannual reports:
