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.

Determinant as the pairing of top exterior powers

Example

On Rn with standard basis e1,,en and dual basis e1,,en, the pairing

e1en, v1vn

is exactly det[v1  vn].

Facts & Assumptions

Given: Vectors v1,,vnRn.

[L1]

The exterior-power pairing on decomposable elements is the determinant of the evaluation matrix (Exterior-power duality pairing).

[L2]

The top exterior power is one-dimensional (The top exterior power is one-dimensional).

Verification

technique · direct
1.1

The matrix with entries ei(vj) is exactly the coordinate matrix [v1  vn] of the ordered n-tuple (v1,,vn).

given
2.1

Applying [L1] to αi=ei gives e1en, v1vn=det(ei(vj))=det[v1  vn].

By [L2], this scalar determines the decomposable top wedge relative to the standard volume form.

Thus the determinant is the top-degree pairing against e1en.

Dependency tree · two levels

7 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.
