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 fundamental-group and minimum-modulus proofs of the fundamental theorem of algebra
The theorem Fundamental theorem of algebra by the fundamental-group obstruction and the published Fundamental theorem of algebra: every nonconstant complex polynomial has a complex root establish the same root-existence statement by genuinely different routes. The fundamental-group proof compares a root-free radial nullhomotopy with the nonzero degree forced by the leading term on a large circle. The minimum-modulus proof instead chooses a point where is least and shows that a positive minimum can be decreased. The first argument spends the calculation of ; the second spends compactness and the local expansion of a polynomial.

Dependency tree · two levels
8 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.
