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.

Why the self-density bound for a dense set carries a 1/X slack

The self-density dG(X,X) counts ordered adjacent pairs of distinct vertices and divides by X2, so the diagonal pairs never contribute. A clique on s vertices therefore has self-density s(s1)/s2=11/s, not 1. That is why the dense conclusion in A c-sparse set has self-density at most c, and a c-dense set has self-density at least 1c1/X carries the reciprocal-size term. The density form of Rödl's theorem absorbs this term by changing its constants and states the cleaner threshold 1ϵ.

Dependency tree · two levels

12 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.
