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.
The spectrum of a field is a one-point affine scheme
Example
For a field , has the sole point . Its local ring, residue field, and ring of global functions are all canonically .
Facts & Assumptions
Given: A field .
The stalk at a prime of an affine spectrum is (The stalk of the affine structure sheaf at a prime is A_p).
Global functions on recover (Global functions on Spec A recover A).
Verification
The only proper ideal of a field is , and it is prime; hence the spectrum has exactly that point.
By [F1], its local ring is , whose residue field is .
By [F2], its global sections are .

Dependency tree · two levels
20 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.
