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.
A normal algebraic extension is one in which every minimal polynomial with a root in the extension splits there
Definition
An algebraic field extension is normal if, for every , the minimal polynomial of over splits over .
Equivalently, every irreducible polynomial that has one root in splits over . Indeed, the monic associate of such a is the minimal polynomial of any one of its roots in , and multiplying by a nonzero scalar does not change whether a polynomial splits.
