Bicategories

In this file we define typeclass for bicategories.

A bicategory B consists of

• objects a : B,
• 1-morphisms f : a ⟶ b between objects a b : B, and
• 2-morphisms η : f ⟶ g between 1-morphisms f g : a ⟶ b between objects a b : B.

We use u, v, and w as the universe variables for objects, 1-morphisms, and 2-morphisms, respectively.

A typeclass for bicategories extends CategoryTheory.CategoryStruct typeclass. This means that we have

• a composition f ≫ g : a ⟶ c for each 1-morphisms f : a ⟶ b and g : b ⟶ c, and
• an identity 𝟙 a : a ⟶ a for each object a : B.

For each object a b : B, the collection of 1-morphisms a ⟶ b has a category structure. The 2-morphisms in the bicategory are implemented as the morphisms in this family of categories.

The composition of 1-morphisms is in fact an object part of a functor (a ⟶ b) ⥤ (b ⟶ c) ⥤ (a ⟶ c). The definition of bicategories in this file does not require this functor directly. Instead, it requires the whiskering functions. For a 1-morphism f : a ⟶ b and a 2-morphism η : g ⟶ h between 1-morphisms g h : b ⟶ c, there is a 2-morphism whiskerLeft f η : f ≫ g ⟶ f ≫ h. Similarly, for a 2-morphism η : f ⟶ g between 1-morphisms f g : a ⟶ b and a 1-morphism f : b ⟶ c, there is a 2-morphism whiskerRight η h : f ≫ h ⟶ g ≫ h. These satisfy the exchange law whiskerLeft f θ ≫ whiskerRight η i = whiskerRight η h ≫ whiskerLeft g θ, which is required as an axiom in the definition here.

class CategoryTheory.Bicategory (B : Type u) extends CategoryTheory.CategoryStruct : Type (max (max u (v + 1)) (w + 1))

In a bicategory, we can compose the 1-morphisms f : a ⟶ b and g : b ⟶ c to obtain a 1-morphism f ≫ g : a ⟶ c. This composition does not need to be strictly associative, but there is a specified associator, α_ f g h : (f ≫ g) ≫ h ≅ f ≫ (g ≫ h). There is an identity 1-morphism 𝟙 a : a ⟶ a, with specified left and right unitor isomorphisms λ_ f : 𝟙 a ≫ f ≅ f and ρ_ f : f ≫ 𝟙 a ≅ f. These associators and unitors satisfy the pentagon and triangle equations.

Simp-normal form for 2-morphisms

Rewriting involving associators and unitors could be very complicated. We try to ease this complexity by putting carefully chosen simp lemmas that rewrite any 2-morphisms into simp-normal form defined below. Rewriting into simp-normal form is also useful when applying (forthcoming) coherence tactic.

The simp-normal form of 2-morphisms is defined to be an expression that has the minimal number of parentheses. More precisely,

1. it is a composition of 2-morphisms like η₁ ≫ η₂ ≫ η₃ ≫ η₄ ≫ η₅ such that each ηᵢ is either a structural 2-morphisms (2-morphisms made up only of identities, associators, unitors) or non-structural 2-morphisms, and
2. each non-structural 2-morphism in the composition is of the form f₁ ◁ f₂ ◁ f₃ ◁ η ▷ f₄ ▷ f₅, where each fᵢ is a 1-morphism that is not the identity or a composite and η is a non-structural 2-morphisms that is also not the identity or a composite.

Note that f₁ ◁ f₂ ◁ f₃ ◁ η ▷ f₄ ▷ f₅ is actually f₁ ◁ (f₂ ◁ (f₃ ◁ ((η ▷ f₄) ▷ f₅))).
