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 zero module has empty support and no associated primes
Example
For the zero -module, Also the primary-submodule definition does not apply to , because it requires a proper submodule.
Facts & Assumptions
Given: A commutative ring and the zero -module.
Associated primes are prime annihilators of elements (Associated primes of a module).
Support consists of the primes whose localization is nonzero (Support of a module).
Primaryity is defined only for proper submodules (Primary submodules and primary ideals).
Verification
The only element of the zero module is , and its annihilator is the whole ring , which is not a prime ideal of itself. Therefore [L1] gives .
Every localization of the zero module is again the zero module, so [L2] gives .
The inclusion is not proper, so [L3] shows that it is not a candidate for the primary-submodule definition. This is the exact boundary that prevents a vacuous use of primaryity at the zero module.
Thus the zero module sits outside associated-prime and primaryity claims in exactly the stated way.

Dependency tree · two levels
10 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.
