  skos:definition "In mathematics, an algebraic structure consists of a nonempty set A (called the underlying set, carrier set or domain), a collection of operations on A (typically binary operations such as addition and multiplication), and a finite set of identities, known as axioms, that these operations must satisfy. An algebraic structure may be based on other algebraic structures with operations and axioms involving several structures. For instance, a vector space involves a second structure called a field, and an operation called scalar multiplication between elements of the field (called scalars), and elements of the vector space (called vectors). (Wikipedia, The Free Encyclopedia, <a href=\"https://en.wikipedia.org/wiki/Algebraic_structure\" target=\"_blank\">https://en.wikipedia.org/wiki/Algebraic_structure</a>)"@en, "En mathématiques, une structure algébrique est définie axiomatiquement par une ou plusieurs opérations sur un ensemble (dites internes), éventuellement muni d’autres opérations (externes) dépendant d’autres ensembles, toutes ces opérations satisfaisant certaines relations telles que l’associativité, la commutativité ou la distributivité.
