Alphabeta MathHow 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 finite separable extension has only finitely many intermediate fields
Statement
Every finite separable extension has only finitely many intermediate fields.
Facts & Assumptions
Given: A finite separable extension .
Every finite separable extension is simple (A finite extension generated by elements all but possibly one of which are separable is simple).
A simple finite extension has finitely many intermediate fields (A simple finite extension has only finitely many intermediate fields).
Proof
By [L1], write for one element .
The conclusion now follows from [L2].
