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.
Nilpotent endomorphisms and their nilpotency index
Definition
An endomorphism is nilpotent if for some positive integer . Its nilpotency index is the least positive integer such that ; this least exponent exists by the well-ordering principle (The well-ordering principle).
The unique endomorphism of the zero space is nilpotent. With the same least-positive-exponent convention, its nilpotency index is because its identity and zero endomorphisms coincide.

Dependency tree · two levels
12 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.
