**Date:**- November 19th - November 25th, 2006
**Organizers:**- Peter Littelmann, Köln
- Nicolai Reshetikhin, Berkeley
**Programme:**-
The most significant results in mathematics are
obtained when combining methods and ideas from different fields of
mathematics and different scientific schools. Representation
theory has always been an important tool in many areas of
mathematics and theoretical physics. Naturally, questions motivated by
applications have strongly influenced research in representation theory
In this Oberwolfach seminar we are going to work out three aspects
of this mutual influence.
The first course focuses on algebraic-geometric aspects of representation theory. Kari Vilonen (Chicago) will give in his lectures an introduction into the geometric Langlands program and also report on latest developments.

The second course will be held by Nicolai Reshetikhin (Berkeley). He will focus on aspects of statistical mechanics related to the representation theory of $gl_\infty$, to statistics of various plane partitions.

Some recent developments in representation theory motivated by theoretical physics will be represented in Tetsuji Miwa’s course (Kyoto) on the construction of monomial basis of representations of vertex operator algebras. The key words here are Bosonic vertex operators, the affine $sl_2$-Kac-Moody algebra and Virasoro minimal series.

**Prerequisites:**- A necessary background for the seminar is the knowledge of representation theory of semisimple Lie algebras or semisimple algebraic groups, or compact groups. Some basic knowledge on the theory of affine Kac-Moody groups and/or algebras is recommended.
