Organizers: Erhard Neher and Kirill Zainoulline
Description:
The theory of Lie algebras and the theory of torsors are well-established areas of modern mathematics. The first deals with the study and classification of (in-)finite dimensional Lie algebras and their representations and has many applications in geometry, combinatorics and mathematical physics. The second studies and classifies so-called twisted forms of algebraic objects (example: associative algebras that become matrix algebras after extending the base field to an algebraic closure), and has many applications in algebraic geometry and number theory. The bridge between these two areas is provided by the Galois cohomology, an invariant which has been extensively studied during the last decades.
The purpose of the mini-workshop is to bring together specialists and young researchers (PhD's and postdocs) in these areas to discuss recent developments and results, to provide an overview of the current research and applications, and to advertise the area among students.
During the workshop Prof. Skip Garibaldi (Emory University, USA) will give two introductory lectures on "cohomological invariants of linear algebraic groups", aimed for graduate students.
