Abstract
Let H be a commutative coassociative Hopf algebra over a field K; then
Ext(H)(K, K) is a DGA. Suppose M is a right DGA-module over this DGA.
We give a new Massey product on this module and prove the basic prope
rties of this Massey product. We have also discussed the case when M i
s a left DGA-module. (C) 1996 Academic Press, Inc.
