Actions from a monoidal category on a category

Given a monoidal category C, and a category D, we define a left action of C on D as the data of an object c ⊙ₗ d of D for every c : C and d : D, as well as the data required to turn - ⊙ₗ - into a bifunctor, along with structure natural isomorphisms (- ⊗ -) ⊙ₗ - ≅ - ⊙ₗ - ⊙ₗ - and 𝟙_ C ⊙ₗ - ≅ -, subject to coherence conditions.

We also define right actions, for these, the notation for the action of c on d is d ⊙ᵣ c, and the structure isomorphisms are of the form - ⊙ᵣ (- ⊗ -) ≅ (- ⊙ᵣ -) ⊙ᵣ - and - ⊙ₗ 𝟙_ C ≅ -.

A class that carries the non-Prop data required to define a left action of a monoidal category C on a category D, to set up notations.

• actionObj : C → D → D

  The left action on objects. This is denoted c ⊙ₗ d.

• actionHomLeft {c c' : C} (f : c ⟶ c') (d : D) : actionObj c d ⟶ actionObj c' d

  The left action of a map f : c ⟶ c' in C on an object d in D. If we are to consider the action as a functor Α : C ⥤ D ⥤ D, this is (Α.map f).app d. This is denoted f ⊵ₗ d`

• actionHomRight (c : C) {d d' : D} (f : d ⟶ d') : actionObj c d ⟶ actionObj c d'

  The action of an object c : C on a map f : d ⟶ d' in D. If we are to consider the action as a functor Α : C ⥤ D ⥤ D, this is (Α.obj c).map f. This is denoted c ⊴ₗ f`.

• actionHom {c c' : C} {d d' : D} (f : c ⟶ c') (g : d ⟶ d') : actionObj c d ⟶ actionObj c' d'

  The action of a pair of maps f : c ⟶ c' and d ⟶ d'. By default, this is defined in terms of actionHomLeft and actionHomRight.

• actionAssocIso (c c' : C) (d : D) : actionObj (tensorObj c c') d ≅ actionObj c (actionObj c' d)

  The structural isomorphism (c ⊗ c') ⊙ₗ d ≅ c ⊙ₗ (c' ⊙ₗ d).

• actionUnitIso (d : D) : actionObj (tensorUnit C) d ≅ d

  The structural isomorphism between 𝟙_ C ⊙ₗ d and d.

A MonoidalLeftAction C D is is the data of:

• For every object c : C and d : D, an object c ⊙ₗ d of D.
• For every morphism f : (c : C) ⟶ c' and every d : D, a morphism f ⊵ₗ d : c ⊙ₗ d ⟶ c' ⊙ₗ d.
• For every morphism f : (d : D) ⟶ d' and every c : C, a morphism c ⊴ₗ f : c ⊙ₗ d ⟶ c ⊙ₗ d'.

• A structure isomorphism αₗ c c' d : c ⊗ c' ⊙ₗ d ≅ c ⊙ₗ c' ⊙ₗ d.
• A structure isomorphism λₗ d : (𝟙_ C) ⊙ₗ d ≅ d. Furthermore, we require identities that turn - ⊙ₗ - into a bifunctor, ensure naturality of αₗ and λₗ, and ensure compatibilies with the associator and unitor isomorphisms in C.
