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 differential of a constant map is zero

Example

If $F : M \to N$ is constant, then $d F_{p} = 0$ for every $p \in M$ .

Facts & Assumptions

Given: A constant smooth map $F : M \to N$ .

[F1]

The differential acts by pullback of target germs (The differential of a smooth map).

Verification

technique · direct

1.1

For any target germ $[g]$ , the composite $g \circ F$ is constant near every point of $M$ .

F1given

1.2

Every derivation annihilates constant germs, so $d F_{p} (v) ([g]) = 0$ for every $v \in T_{p} M$ .

F1givenalgebra

2.1

Hence $d F_{p} = 0$ .

Dependency tree · two levels

2 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.
