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.
Eventual homotopy vanishing of the motivic tower
PDF p. 4: Motivic graded spectral sequence; PDF p. 9: Eventual filtration vanishing
Statement
Assume the Axiom of Choice. Let be a finite-dimensional Noetherian equicharacteristic scheme of Krull dimension , with equicharacteristic meaning that its structure map factors through or . Use the actual source motivic filtration on that prime-field category; on schemes over the standing field this is exactly the completed local filtration. Then for each fixed integer used in the article there is such that Indeed the same eventual vanishing holds in every fixed integer homotopy degree. The threshold may depend on that degree. The finite-valuative-dimension requirement of the source is satisfied because for Noetherian schemes. This is vanishing of the actual stage groups, stronger than merely vanishing of their images in .
Facts & Assumptions
Given: The Axiom of Choice and the stated Noetherian finite-dimensional scheme and actual compatible source filtration.
Goal: Supply the exact eventual-stage assertion used in the article without narrowing the original scheme scope.
The local valuative convention matches the source convention and General equicharacteristic scope and the standing filtration restriction match the dimension convention and check the complete source domain.
The precise source stage bound and its homotopy interpretation supplies the actual stagewise bound; Explicit eventual-stage thresholds in every fixed homotopy degree produces the required thresholds.
Degreewise boundedness and finite collections of eventual vanishings records the equivalent degreewise property and finite-degree compatibility without asserting an unqualified uniform bound.
The assumed The Axiom of Choice discharges the inherited Choice premises of [F1]–[F3] and Motivic filtration and image groups when their selected actual source tower and perfect-complex -theory realization are used. It adds no restriction to the geometric scope of .
Every actual motivic stage on the empty scheme is zero proves zero actual stages on the empty scheme without invoking nonempty-scheme suppliers or a descent property of the stages.
Proof
If is empty, [F5] gives all stage vanishings at every integer index, so the eventual assertion holds for any integer anchor without using a source empty-dimension convention. Suppose henceforth that is nonempty. Under the inherited Choice premise in [F4], by [F1] the scheme is in the source’s qcqs prime-field domain and has finite source valuative dimension. The source boundedness theorem therefore gives and the stagewise homotopy interpretation of [F2]. When is over the standing field, these are the same actual stage maps as the completed local definition.
Apply the threshold lemma of [F2] with anchor . It gives the conclusion for each fixed , including all the nonpositive degrees required by the article. The local degreewise statement and finite-set version are [F3]. This proves the full proposition.
