Pseudofunctors

A pseudofunctor is an oplax (or lax) functor whose mapId and mapComp are isomorphisms. We provide several constructors for pseudofunctors:

• Pseudofunctor.mk : the default constructor, which requires map₂_whiskerLeft and map₂_whiskerRight instead of naturality of mapComp.

• Pseudofunctor.mkOfOplax : construct a pseudofunctor from an oplax functor whose mapId and mapComp are isomorphisms. This constructor uses Iso to describe isomorphisms.

• pseudofunctor.mkOfOplax' : similar to mkOfOplax, but uses IsIso to describe isomorphisms.

• Pseudofunctor.mkOfLax : construct a pseudofunctor from a lax functor whose mapId and mapComp are isomorphisms. This constructor uses Iso to describe isomorphisms.

• pseudofunctor.mkOfLax' : similar to mkOfLax, but uses IsIso to describe isomorphisms.

Main definitions

• CategoryTheory.Pseudofunctor B C : a pseudofunctor between bicategories B and C
• CategoryTheory.Pseudofunctor.comp F G : the composition of pseudofunctors

structure CategoryTheory.Pseudofunctor (B : Type u₁) [CategoryTheory.Bicategory B] (C : Type u₂) [CategoryTheory.Bicategory C] extends CategoryTheory.PrelaxFunctor B C : Type (max (max (max (max (max u₁ u₂) v₁) v₂) w₁) w₂)

A pseudofunctor F between bicategories B and C consists of a function between objects F.obj, a function between 1-morphisms F.map, and a function between 2-morphisms F.map₂.

Unlike functors between categories, F.map do not need to strictly commute with the compositions, and do not need to strictly preserve the identity. Instead, there are specified 2-isomorphisms F.map (𝟙 a) ≅ 𝟙 (F.obj a) and F.map (f ≫ g) ≅ F.map f ≫ F.map g.

F.map₂ strictly commute with compositions and preserve the identity. They also preserve the associator, the left unitor, and the right unitor modulo some adjustments of domains and codomains of 2-morphisms.
