Abstract

Using a local lemma, we show that the d-th de Rham group of an oriented, compact, connected d-dimensional manifold is canonically isomorphic to R (7.2.1). From this fundamental fact we deduce Moser’s theorem, which says that two volume forms whose integral is the same are conjugate under a diffeomorphism.
