We propose the following principle to study pointed Hopf algebras, or more generally, Hopf algebras whose coradical is a Hopf subalgebra. Given such a Hopf algebra A, consider its coradical filtration and the associated graded coalgebra gr A. Then gr A is a graded Hopf algebra, since the coradical A

The purpose of this paper is to give a ''universal'' construction of Hopf algebras over any commutative ring. The mod-p Steenrod algebras are all examples of this construction; other examples of Hopf algebras related to the mod-p Steenrod algebras are also produced. Then we give an argument to produ
We study forms of coalgebras and Hopf algebras i.e., coalgebras and Hopf . algebras which are isomorphic after a suitable extension of the base field . We classify all forms of grouplike coalgebras according to the structure of their simple subcoalgebras. For Hopf algebras, given a W \*-Galois field
We give a structure theorem for pointed Hopf algebras of dimension p 3 , having coradical kC , where k is an algebraically closed field of characteristic zero. p Combining this with previous results, we obtain the complete classification of all pointed Hopf algebras of dimension p 3 .
