Universal algebra From Wikipedia, the free encyclopedia. Universal algebra is the field of mathematics that studies the ideas common to all algebraic structures Contents Basic idea Examples Groups Modules ... edit Basic idea From the point of view of universal algebra, an algebra (or abstract algebra ) is a set A together with a collection of operations on A . An n ary operation on A is a function that takes n elements of A and returns a single element of A . Thus, a 0-ary operation (or nullary operation ) is simply an element of A , or a constant , often denoted by a letter like a . A 1-ary operation (or unary operation ) is simply a function from A to A , often denoted by a symbol placed in front of its argument, like ~ x . A 2-ary operation (or binary operation ) is often denoted by a symbol placed between its arguments, like x y . Operations of higher or unspecified arity are usually denoted by function symbols, with the arguments placed in parentheses and separated by commas, like f x y z ) or f x x n ). Some researchers allow infinitary operations, such as , allowing the algebraic theory of complete lattices to be studied.

Variety (universal algebra) From Wikipedia, the free encyclopedia. In universal algebra , a variety of algebras is the class of all algebraic structures of a given signature satisfying a given set of identities . Equivalently, a variety is a class of algebraic structures of the same signature which is closed under the taking of homomorphic images, subalgebras and cartesian products A variety of algebras should not be confused with an algebraic variety . Intuitively, a variety of algebras is an equationally defined collection of algebras , while an algebraic variety is an equationally defined collection of elements from a single algebra . The two are named alike by analogy, but they are formally quite distinct and their theories have little in common. edit Birkhoff's theorem The equivalence of the two definitions given above is of fundamental importance in universal algebra. It was proved by Garrett Birkhoff , and is generally known as Birkhoff's theorem , or as the HSP theorem (H, S and P standing respectively for the closure operations of homomorphism subalgebra and product Formally, suppose we fix a

Sakharov Universal Algebra Universal algebra studies common properties of all algebraic structures, including groups rings fields lattices , etc. A universal algebra is a pair , where and are sets and for each is an operation on . The algebra is finitary if each of its operations is finitary. A set of function symbols (or operations) of degree is called a signature (or type). Let be a signature. An algebra is defined by a domain (which is called its carrier or universe) and a mapping that relates a function to each -place function symbol from Let and be two algebras over the same signature , and their carriers are and , respectively. A mapping is called a homomorphism from to if for every and all If a homomorphism is onto , then it is called epimorphism . If is an epimorphism , then is called a homomorphic image of . If the homomorphism is a bijection , then it is called an isomorphism . On the class of all algebras, define a relation
