Gelfand–Fuks cohomology

In mathematics, Gelfand–Fuks cohomology, introduced in, is a cohomology theory for Lie algebras of smooth vector fields. It differs from the Lie algebra cohomology of Chevalley-Eilenberg in that its cochains are taken to be continuous multilinear alternating forms on the Lie algebra of smooth vector fields where the latter is given the $$C^{\infty}$$ topology.
