We characterize noncommutative Frobenius algebras A in terms of the existence of a coproduct which is a map of left A e -modules. We show that the category Ε½ . of right left comodules over A, relative to this coproduct, is isomorphic to the Ε½ . category of right left modules. This isomorphism enable
