How statement and proof provenance work

The first chip identifies the source of the statement or construction; the second identifies the source of its local proof or verification.

  • Literature-sourced: the exact statement appears in a cited source; only wording and notation differ.
  • AI-adapted: a semantically identical restatement of literature-sourced material, modulo indexing, notation, and boundary cases adopted by the library.
  • AI-generated: a genuinely novel statement formulated by AI, with no source for the claim itself.

These labels describe origin, not correctness: citations and verification chips remain separate evidence.

Enriched weighted limit

Definition

Assume V is symmetric monoidal right closed and its collection of objects is a set, so that it is enriched in itself and enriched opposites are defined using the symmetry (A closed monoidal category is enriched in itself). Let A be a small V-category, let T:AB be a V-functor, and let W:AV be a V-functor (Enriched functor).

An enriched weighted limit of T by W is an object {W,T} of B together with an isomorphism in V

B(B,{W,T})[A,V](W,B(B,T))

natural in B, whenever the enriched functor category and the displayed hom-object are formed. Dually, for a weight on Aop, an enriched weighted colimit is an object WT with

B(WT,B)[Aop,V](W,B(T,B))

natural in B.

This is the direct enriched analogue of Set-weighted limits and colimits: sets are replaced by objects of V, hom-sets by enriched hom-objects, and ordinary natural transformations by enriched ones.

Dependency tree · two levels

15 results within two dependency steps of this one, each drawn at its shortest distance from it. An arrow runs from a result to what uses it, so the chart reads left to right and ends at this result, which carries a heavier outline. Every node is a link to that result.
