Koszul Duality Patterns in Representation Theory
- A. Beilinson, V. Ginzburg, W. Soergel
- Mathematics
- 1996
The aim of this paper is to work out a concrete example as well as to provide the general pattern of applications of Koszul duality to repre- sentation theory. The paper consists of three parts…

Representations of quantum groups at a p-th root of unity and of semisimple groups in characteristic p : independence of p
- H. H. Andersen, J. Jantzen, W. Soergel
- Chemistry
- 1994
The method disclosed herein may be practiced by passing the vapors to be sampled along a path with halogen vapor, preferably chlorine vapor, heating the mixed vapors to halogenate those of the…
Character formulas for tilting modules over Kac-Moody algebras
- W. Soergel
- Mathematics
- 28 December 1998
We show how to express the characters of tilting modules in a (possibly parabolic) category O over a Kac-Moody algebra in terms of the characters of simple highest weight modules. This settles, in…
Kazhdan-Lusztig polynomials and a combinatoric for tilting modules
- W. Soergel
- Mathematics
- 5 May 1997
This article gives a self-contained treatment of the theory of Kazhdan-Lusztig polynomials with special emphasis on affine reflection groups. There are only a few new results but several new proofs.…

The composition series of modules induced from Whittaker modules
- D. Miličić, W. Soergel
- Mathematics
- 31 December 1997
AbstractWe study a category of representations over a semisimple Lie algebra, which contains category
$ \cal O $ as well as the so-called Whittaker modules, and prove a generalization of the…
n-Cohomology of simple highest weight modules on walls and purity
- W. Soergel
- Mathematics
- 1 October 1989
SummaryLetG⊃P⊃B be respectively a complex connected linear algebraic semisimple group, a parabolic subgroup and a Borel subgroup. The first main result is the following theorem: Let ℱ be a pure…
