The Banff International Research Station will host the "Lie algebras, torsors and cohomological invariants" workshop from September 30th to October 5th, 2012.

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 has many applications in representation theory, combinatorics and mathematical physics. The second studies and classifies so-called twisted forms of algebraic objects and has many applications in algebraic geometry and number theory. The bridge between Lie algebras and torsors is provided by various cohomological invariants.

The purpose of this interdisciplinary activity is to bring together specialists and young researchers to establish new links and projects and to advertise these research areas.

The Banff International Research Station for Mathematical Innovation and Discovery (BIRS) is a collaborative Canada-US-Mexico venture that provides an environment for creative interaction as well as the exchange of ideas, knowledge, and methods within the Mathematical Sciences, with related disciplines and with industry. The research station is located at The Banff Centre in Alberta and is supported by Canada's Natural Science and Engineering Research Council (NSERC), the U.S. National Science Foundation (NSF), Alberta's Advanced Education and Technology, and Mexico's Consejo Nacional de Ciencia y Tecnología (CONACYT).
