摘要

The authors discuss a method to construct a De Rham complex (differentialalgebra) of Poincare-Birkhoff-Witt-type on the universal enveloping algebra of a Lie algebra g. The authors determine the cases in which this gives rise to 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.
