Subalgebra — In algebra (mathematics), the word algebra usually means a vector space or module equipped with an additional bilinear operation. Algebras in universal algebra are far more general: they are a common generalisation of all algebraic structures. In … Wikipedia
Subálgebra — Portal:Matemática. Contenido relacionado con Matemática. En álgebra abstracta, un subálgebra de un álgebra A es un subgrupo S de A que también tiene la estructura de un álgebra del mismo tipo cuando las operaciones algebraicas se restringuen a S … Wikipedia Español
Cartan subalgebra — In mathematics, a Cartan subalgebra is a nilpotent subalgebra mathfrak{h} of a Lie algebra mathfrak{g} that is self normalising (if [X,Y] in mathfrak{h} for all X in mathfrak{h}, then Y in mathfrak{h}).Cartan subalgebras exist for finite… … Wikipedia
Hereditary C*-subalgebra — In operator algebras, a hereditary C* subalgebra of a C* algebra A is a particular type of C* subalgebra whose structure is closely related to that of A . A C* subalgebra B of A is a hereditary C* subalgebra if for all 0 le; a le; b , where b… … Wikipedia
Fuzzy subalgebra — Fuzzy subalgebras theory is a chapter of fuzzy set theory. It is obtained from an interpretation in a multi valued logic of axioms usually expressing the notion of subalgebra of a given algebraic structure. Indeed, consider a first order language … Wikipedia

Boolean algebras canonically defined — Boolean algebras have been formally defined variously as a kind of lattice and as a kind of ring. This article presents them more neutrally but equally formally as simply the models of the equational theory of two values, and observes the… … Wikipedia
Algebra over a field — This article is about a particular kind of vector space. For other uses of the term algebra , see algebra (disambiguation). In mathematics, an algebra over a field is a vector space equipped with a bilinear vector product. That is to say, it is… … Wikipedia
Heyting algebra — In mathematics, Heyting algebras are special partially ordered sets that constitute a generalization of Boolean algebras, named after Arend Heyting. Heyting algebras arise as models of intuitionistic logic, a logic in which the law of excluded… … Wikipedia
Biquaternion — In abstract algebra, the biquaternions are the numbers where w, x, y, and z are complex numbers and the elements of {1, i, j, k} multiply as in the quaternion group. As there are three types of complex number, so there are three types of… … Wikipedia
