Abstract
Let H be a Hopf algebra, H. be a sub-Hopf algebra of H, H. be the quotient Hopt algebra of H modular H..This paper gives a simplified complex by defining a new base for the cobar complex and proves that the cobar complex of H has the same cohomology algebra with a twisted product of the cobar complexes of H. and H.
