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.
Deck transformations and the deck-transformation group of a covering
Definition
For a covering , a deck transformation is an isomorphism over , so (Maps and isomorphisms of covering spaces over a fixed base). Deck transformations form the deck group under composition, and this group acts on by evaluation (Group and abelian group, Left group actions, transitive actions, and faithful actions).
