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 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 E/F.

[L2]

A simple finite extension has finitely many intermediate fields (A simple finite extension has only finitely many intermediate fields).

Proof

technique · direct
1.1L1

By [L1], write E=F(α) for one element α.

2.1step 1.1L2∎

The conclusion now follows from [L2].

Dependency tree · two levels

11 results within two dependency steps of this one, each drawn at its shortest distance from it. An arrow runs from a result to what uses it, so the chart reads left to right and ends at this result, which carries a heavier outline. Every node is a link to that result.
