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.

Lie derivative of forms is a degree-zero graded derivation

Statement

For forms $α, β$ , $L_{X} (α \land β) = (L_{X} α) \land β + α \land (L_{X} β)$ .

Facts & Assumptions

Given: The manifolds, forms, vector fields, maps, and coordinates explicitly named in the statement.

[F1]

The preceding result states that For $ω \in Ω^{k} (M)$ , $L_{X} ω$ is the Lie derivative of $ω$ regarded as an alternating covariant tensor. (The Lie derivative of a differential form).

Proof

technique · direct

1.1F1given

The wedge of alternating forms is the alternating restriction of their tensor product.

2.1step 1.1∎

Restricting the tensor product rule for $L_{X}$ to that alternating product yields the degree-zero graded rule.

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.
