Idea

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

Definitions

The precategory of commutative monoids as a full subprecategory of monoids

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

The large precategory of commutative monoids

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

The precategory of small commutative monoids

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