Algèbres de Lie de dimension infinie - cohomologie et déformations

Abstract : Our research concerns the homological algebra and deformation theory of infinite dimensional Lie algebras. We have worked on Gelfand-Fuks cohomology, on crossed modules, on current algebras, their cohomology and their Lie theory together with K.-H. Neeb, on the stack of deformations of Krichever-Novikov algebras, and on deformations of infinite dimensional filiform Lie algebras together with A. Fialowski.
Work on crossed modules of Lie groupoids was joint with C. Laurent-Gengoux, and work on Leibniz cohomology of vector fields on the circle together with A. Frabetti.
