Graded Coalgebras¶

class
sage.categories.graded_coalgebras.
GradedCoalgebras
(base_category)¶ Bases:
sage.categories.graded_modules.GradedModulesCategory
The category of graded coalgebras
EXAMPLES:
sage: C = GradedCoalgebras(QQ); C Category of graded coalgebras over Rational Field sage: C is Coalgebras(QQ).Graded() True

class
SignedTensorProducts
(category, *args)¶ Bases:
sage.categories.signed_tensor.SignedTensorProductsCategory

extra_super_categories
()¶ EXAMPLES:
sage: Coalgebras(QQ).Graded().SignedTensorProducts().extra_super_categories() [Category of graded coalgebras over Rational Field] sage: Coalgebras(QQ).Graded().SignedTensorProducts().super_categories() [Category of graded coalgebras over Rational Field]
Meaning: a signed tensor product of coalgebras is a coalgebra
