# Graded bialgebras

sage.categories.graded_bialgebras.GradedBialgebras(base_ring)

  The category of graded bialgebras.

  EXAMPLES:

  Sage

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

  Python

      >>> from sage.all import *
      >>> C = GradedBialgebras(QQ); C
      Join of Category of graded algebras over Rational Field
          and Category of bialgebras over Rational Field
          and Category of graded coalgebras over Rational Field
      >>> C is Bialgebras(QQ).Graded()
      True
