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.
Pushforwards and pullbacks of vector fields by a diffeomorphism
Definition
Assume , so that and carry their canonical smooth structures. Let be a diffeomorphism.
For a smooth vector field on , the pushforward is the unique vector field on that is -related to . Explicitly,
For a smooth vector field on , the pullback is the vector field on defined by
Because and are smooth and their global differentials are smooth, both constructions yield smooth vector fields.

Dependency tree · two levels
10 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.
