Abstract
This paper studies the structure of U(g)-Galois extensions. In particular, we use a result of Bell to construct a "PBW-like" free basis for faithfully flat U(g)-Galois extensions. We then move to non-faithfully flat extension s and propose a possible equivalent condition for a U(g)-extension to be Ga lois. We get a partial result for this.
