Primes¶
- Idempotence
- … theory**, idempotent functions on a partially ordered set are called closure operators — `cl(cl(S)) = cl(S)` — and provide the foundation for topology (closure of a set), formal-language theory (Kleene closure), and Galois connections, with Tarski (1935) and Kuratowski (1922) supplying the canonical axiomatizations
This source(Establishes closure operators `cl(cl(X)) = cl(X)` as foundational for topology, order theory, and Galois connections; idempotence as defining property.)

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Was it audited? Yes. A second, independent pass read the citation against the article text and recorded a verdict.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
