This is a summer school activity of the SFB/TR 45 financed by Deutsche Forschungsgemeinschaft. It will take place September 17-21, 2007 at the University of Mainz. The workshop is intended to improve the training of PhD students and postdocs in the area, in particular of those inside the SFB/TR 45.


Stefan Gille, Nikita Semenov, Kirill Zainoulline, Markus Rost.


Recent developments in the theory of quadratic forms, Milnor K-Theory and Galois cohomology rises several natural questions concerning the structure of the category of Chow motives. The main question is how to describe its set of generators and relations. Namely, given a variety X to find all possible motivic decompositions of X. In the present workshop we will focus on this question for motives of varieties which admit an action of an algebraic group G. We also discuss relations with torsion indices, canonical dimensions and cohomological invariants.

Here is a more detailed outline of the workshop.


Basic Algebraic Geometry (e.g. level of the book by Hartshorne)
