Oberwolfach Seminar: Representations of Finite Groups: Local Cohomology and Support
- May 23rd - May 29th, 2010
- Dave Benson, Aberdeen
- Srikanth Iyengar, Lincoln
- Henning Krause, Paderborn
- The seminar discusses some unifying themes in commutative algebra, representation theory, and homotopy theory.
The underlying concept is the notion of support which provides a geometric approach for studying various algebraic structures.
In terms of applications, the focus will be on modular representations of finite groups.
In particular, classifications of thick and localizing subcategories of the stable module categories associated to a finite group will be presented.
There will be three series of lectures, starting with background material from group representation theory, commutative algebra,
and the theory of derived categories.
The goal is to explain local cohomology functors for specific triangulated categories and to discuss their applications.
- A solid background in algebra, including the basic theory of rings and modules, basic commutative algebra
(first chapters of Atiyah/MacDonald), and basic homological algebra (derived functors, Ext, Tor).
- The following books include basic material from representation theory, commutative algebra, and the theory of triangulated categories.

- April 1st, 2010
The seminars take place at the
Mathematisches Forschungsinstitut Oberwolfach.
The number of participants is restricted to 25.
The Institute covers accommodation and food.
We are pleased that the Carl Friedrich von Siemens Foundation has decided
to support the Oberwolfach Seminars from summer 2008 to summer 2013.
By this support, travel expenses can be reimbursed up to 200 Euro in average per person.
Participants can ask for travel support during their stay in Oberwolfach at the guest office against copy of travel receipts.
