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.

The measure with density f relative to μ

Definition

Let (X,A,μ) be a measure space and let f:X→[0,+∞] be measurable. The measure with density f relative to μ is the measure f dμ:A→[0,+∞],(f dμ)(A):=∫Af dμ, whose measure property is supplied by The indefinite integral of a nonnegative measurable function is a measure.
