Idea

Gel’fand-Fuks cohomology is the cochain cohomology of continuous alternating chains on the topological algebra of smooth vector fields on smooth manifolds, where the topology on the algebra is given by uniform convergence of all (higher) partial derivative on compact subsets (sometimes called C C^\infty-topology on that algebra).
