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 ACω, so that TM and TN carry their canonical smooth structures. Let F:MN be a diffeomorphism.

For a smooth vector field X on M, the pushforward FX is the unique vector field on N that is F-related to X. Explicitly,

(FX)F(p):=dFp(Xp).

For a smooth vector field Y on N, the pullback FY is the vector field on M defined by

(FY)p:=d(F1)F(p)(YF(p)).

Because F and F1 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.
