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.

Negative homology of the cycle complex

PDF p. 13: CH3 identification and degree seven vanishing

Statement

For a field k, a smooth finite-type k-scheme X, r≥0, and an integer n<0, one has Hnzr(X,∙)=0.

Facts & Assumptions

Given: k, X, r and n as in the statement.

Goal: Compute the indicated homology group.

[F1]

The Bloch complex has zero chain group in every negative degree, and its homology is the kernel modulo the image. Bloch cycle complexes and higher Chow groups

Proof

1.1F1

Since n<0, the chain group in degree n is zero, so the kernel of its outgoing differential is zero.

2.1F1step 1.1∎

The incoming image is a subgroup of this zero kernel; consequently their quotient is zero.
