About: Étale algebra

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In commutative algebra, an étale algebra over a field is a special type of algebra, one that is isomorphic to a finite product of finite separable field extensions. These may also be called separable algebras, though the latter term is sometimes used in a broader sense.

Property Value
dbo:abstract
  • En mathématiques, une algèbre étale sur un corps commutatif K est une K-algèbre produit d'un nombre fini d'extensions finies séparables de K. Les algèbres étales sur K ne sont autres que les algèbres séparables commutatives sur K. (fr)
