Graded Hopf algebras

sage.categories.graded_hopf_algebras.GradedHopfAlgebras(base_ring)

The category of graded Hopf algebras.

EXAMPLES:

sage: C = GradedHopfAlgebras(QQ); C
Join of Category of hopf algebras over Rational Field
    and Category of graded algebras over Rational Field
sage: C is HopfAlgebras(QQ).Graded()
True

TESTS:

sage: TestSuite(C).run()
