The monoidal category structures on graded objects

Assuming that C is a monoidal category and that I is an additive monoid, we introduce a partially defined tensor product on the category GradedObject I C: given X₁ and X₂ two objects in GradedObject I C, we define GradedObject.Monoidal.tensorObj X₁ X₂ under the assumption HasTensor X₁ X₂ that the coproduct of X₁ i ⊗ X₂ j for i + j = n exists for any n : I.

Under suitable assumptions about the existence of coproducts and the preservation of certain coproducts by the tensor products in C, we obtain a monoidal category structure on GradedObject I C. In particular, if C has finite coproducts to which the tensor product commutes, we obtain a monoidal category structure on GradedObject ℕ C.
