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.

Rings of integers are Dedekind domains

Statement

Assume the Axiom of Choice. The ring of integers of every number field is a Dedekind domain.

Facts & Assumptions

Given: The Axiom of Choice and a number field K.

[F1]

Assuming Choice, the integral closure of a Dedekind domain in a finite separable extension is Dedekind (The integral closure of a Dedekind domain in a finite separable extension is Dedekind).

Proof

technique · direct
1.1

Apply [F1] with base ring Z and extension K/Q.

F1given
2.1

Its integral closure is precisely OK, so it is Dedekind.

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.
