Domain-specific¶
- Étale Algebra
- This yields a contravariant equivalence between finite étale `k`-algebras and finite continuous `G_k`-sets
This sourceFor the anti-equivalence of §1.5 between finite étale k-algebras and finite continuous Galois sets, contravariance included. For the splitting statement — base change to a separable closure turns a finite étale k-algebra of dimension n into (k^s)^n — proved in §1.5.

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? Read against the text for 1 of 1 citation: 1 supported. Each verdict is shown under its citation below, with what in the work backs the sentence.
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.
