The action of bifunctors on graded objects #
Given a bifunctor F : C₁ ⥤ C₂ ⥤ C₃ and types I and J, we construct an obvious functor
mapBifunctor F I J : GradedObject I C₁ ⥤ GradedObject J C₂ ⥤ GradedObject (I × J) C₃.
When we have a map p : I × J → K and that suitable coproducts exists, we also get
a functor
mapBifunctorMap F p : GradedObject I C₁ ⥤ GradedObject J C₂ ⥤ GradedObject K C₃.
In case p : I × I → I is the addition on a monoid and F is the tensor product on a monoidal
category C, these definitions shall be used in order to construct a monoidal structure
on GradedObject I C (TODO @joelriou).
