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.
An algebraic closure of a field
Definition
An algebraic closure of a field is a field extension that is algebraic (Algebraic and transcendental elements and algebraic extensions) and whose field is algebraically closed (An algebraically closed field: every nonconstant polynomial has a root in the field). The notation denotes a chosen algebraic closure; it does not specify a preferred one or a preferred isomorphism between two choices.
