Summer School
Geometry and Combinatorics in Representation Theory of Lie Algebras

Crystals, Path-Model, Quiver Varieties

October 4 - 8, 2010
Cologne, Germany

Organizers   Ghislain Fourier (Cologne)    Michael Ehrig (Bonn)
Supported by DFG-Schwerpunkt 1388 "Darstellungstheorie"

Location: Cologne, Physics Institute, "Seminarraum Theoretische Physik" (map)

Intent: To give an introduction to the interaction of geometry and combinatorics in Lie theory. The goal will be to describe the use of geometry to obtain combinatorial objects, like crystals or paths.

Lectures/Talks: There will be 4 mini courses, each consisting of 4 lectures (60 minutes each), given by young leading experts of their respective area of research.
       - Evgeny Feigin (University Higher School of Economics, Moscow)   "Deformed representations of simple Lie algebras: combinatorics and geometry"
       - Stéphane Gaussent (Univesité Henri Poincaré, Nancy)   "Geometry of buildings and representation theory"
       - Alistair Savage (University of Ottawa)   "Geometric realizations of crystals"
       - Mark Shimozono (Virginia Tech)   "Schubert calculus for beginners"
In addition there will be short talks given by the participants and an overview talk about the subject of the school in general by Catharina Stroppel (University of Bonn)

Audience: As a first insight into a large and fast growing field, the school is first and foremost addressed to PhD-students, advanced Undergraduates and early PostDocs (less than 2 years after graduation). To allow effective learning, the number of participants will be limited to roughly 30.

Accomodation/Travel Support: The school is supported by the DFG-Schwerpunkt "1388 Darstellungstheorie" and some funding for accomodation and travel expenses are offered. If you would like to apply for funding, please let us know in your application (a rough estimate of your travel costs would be appreciated as well)

Application: Via Email to or, please include a short abstract if you are interested in giving a talk and if you are a PostDoc the date of your graduation.

Deadline for applications for funding July, 22nd.

Deadline for applications without funding August, 31st.
