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 Lie derivative of a tensor field

Definition

If X has local flow Φt and T is a smooth tensor field of type (r,s), its Lie derivative is LXT=ddt∣t=0Φt∗T, on every local flow domain where this derivative is defined. Here the pullback by the local diffeomorphism Φt acts by dΦ−t on each contravariant slot and by dΦt on each covariant slot.
