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.

FALSE: a conical limit in an enriched category is just a limit in the underlying category

Statement

A conical limit in an enriched category is nothing more than an ordinary limit in the underlying category.

Facts & Assumptions

Given: The conical-limit comparison results from the A page.

[L2]

A conical enriched limit is stronger than an underlying ordinary limit (A conical enriched limit is stronger than a limit in the underlying category).

Refutation

1.1given

If the statement were true, then conical enriched limits and underlying ordinary limits would coincide.

1.2L2construct

A concrete failure occurs for V=Cat. Let M be the strict 2-category freely generated by objects a,b, a 1-cell f:a→b, and a nonidentity 2-cell α:f⇒f. Its underlying category is the walking-arrow category, so b is the ordinary product b×b. But a conical product would require M(a,b)≅M(a,b)×M(a,b) as categories. Here M(a,b) is the one-object category with endomorphism monoid N, which is not isomorphic to its square. Thus this ordinary product is not conical.

2.1step 1.2∎

Hence the converse of [L2] fails: an underlying ordinary limit need not satisfy the enriched conical universal property. The displayed statement is false.

5 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.
