Graded bialgebras

sage.categories.graded_bialgebras.GradedBialgebras(base_ring)

The category of graded bialgebras

EXAMPLES:

sage: C = GradedBialgebras(QQ); C
Join of Category of graded algebras over Rational Field
    and Category of bialgebras over Rational Field
sage: C is Bialgebras(QQ).Graded()
True

TESTS:

sage: TestSuite(C).run()
