Monoidal categories

A monoidal category is a category equipped with a tensor product, unitors, and an associator. In the definition, we provide the tensor product as a pair of functions

• tensorObj : C → C → C
• tensorHom : (X₁ ⟶ Y₁) → (X₂ ⟶ Y₂) → ((X₁ ⊗ X₂) ⟶ (Y₁ ⊗ Y₂)) and allow use of the overloaded notation ⊗ for both. The unitors and associator are provided componentwise.

The tensor product can be expressed as a functor via tensor : C × C ⥤ C. The unitors and associator are gathered together as natural isomorphisms in leftUnitor_nat_iso, rightUnitor_nat_iso and associator_nat_iso.

Some consequences of the definition are proved in other files after proving the coherence theorem, e.g. (λ_ (𝟙_ C)).hom = (ρ_ (𝟙_ C)).hom in CategoryTheory.Monoidal.CoherenceLemmas.

Implementation notes

In the definition of monoidal categories, we also provide the whiskering operators:

• whiskerLeft (X : C) {Y₁ Y₂ : C} (f : Y₁ ⟶ Y₂) : X ⊗ Y₁ ⟶ X ⊗ Y₂, denoted by X ◁ f,
• whiskerRight {X₁ X₂ : C} (f : X₁ ⟶ X₂) (Y : C) : X₁ ⊗ Y ⟶ X₂ ⊗ Y, denoted by f ▷ Y. These are products of an object and a morphism (the terminology "whiskering" is borrowed from 2-category theory). The tensor product of morphisms tensorHom can be defined in terms of the whiskerings. There are two possible such definitions, which are related by the exchange property of the whiskerings. These two definitions are accessed by tensorHom_def and tensorHom_def'. By default, tensorHom is defined so that tensorHom_def holds definitionally.

If you want to provide tensorHom and define whiskerLeft and whiskerRight in terms of it, you can use the alternative constructor CategoryTheory.MonoidalCategory.ofTensorHom.

The whiskerings are useful when considering simp-normal forms of morphisms in monoidal categories.

In a monoidal category, we can take the tensor product of objects, X ⊗ Y and of morphisms f ⊗ g. Tensor product does not need to be strictly associative on objects, but there is a specified associator, α_ X Y Z : (X ⊗ Y) ⊗ Z ≅ X ⊗ (Y ⊗ Z). There is a tensor unit 𝟙_ C, with specified left and right unitor isomorphisms λ_ X : 𝟙_ C ⊗ X ≅ X and ρ_ X : X ⊗ 𝟙_ C ≅ X. These associators and unitors satisfy the pentagon and triangle equations.
