Abstract
We discuss a method to construct a De Rham complex (differential algeb ra) of Poincare-Birkhoff-Witt type on the universal enveloping algebra of a Lie algebra g. We determine the cases in which this gives rise t o a differential Hopf algebra that naturally extends the Hopf algebra structure of U(g) The construction of such differential structures is interpreted in terms of color Lie superalgebras.
