Abstract

In this paper, we study the structures of monomial Hopf algebras over a field of positive characteristic. A necessary and sufficient condition for the monomial coalgebra C d (n) to admit Hopf structures is given here, and if it is the case, all graded Hopf structures on C d (n) are completely classified. Moreover, we construct a Hopf algebras filtration on C d (n) which will help us to discuss a conjecture posed by Andruskiewitsch and Schneider. Finally combined with a theorem by Montgomery, we give the structure theorem for all monomial Hopf algebras.
