Domain-specific

• Extensive category
  • A category is extensive when the canonical functor from the product of slice categories over X and Y to the slice over X+Y is an equivalence, encoding universal disjoint decomposition.
  • … instance directly demonstrates that finite coproducts exist and for every X and Y the canonical functor from C/X times C/Y to C/(X+Y) is an equivalence under the declared size convention. to An applied instance preserves the same invariant under a changed scale, notation, jurisdiction, dataset, or implementation..
