Idea

The precategory of commutative rings consists of commutative rings and homomorphisms of commutative rings.

Definitions

The precategory of commutative rings as a full subprecategory of rings

Commutative-Ring-Full-Large-Subprecategory :
  Full-Large-Subprecategory (λ l → l) Ring-Large-Precategory
Commutative-Ring-Full-Large-Subprecategory = is-commutative-prop-Ring

The large precategory of commutative rings

Commutative-Ring-Large-Precategory : Large-Precategory lsuc (_⊔_)
Commutative-Ring-Large-Precategory =
  large-precategory-Full-Large-Subprecategory
    ( Ring-Large-Precategory)
    ( Commutative-Ring-Full-Large-Subprecategory)

The precategory of commutative rings of universe level l

Commutative-Ring-Precategory : (l : Level) → Precategory (lsuc l) l
Commutative-Ring-Precategory =
  precategory-Large-Precategory Commutative-Ring-Large-Precategory
