http://en.wikipedia.org/wiki/Universal_algebra

Extractions: From Wikipedia, the free encyclopedia Jump to: navigation search Universal algebra (sometimes called general algebra ) is the field of mathematics that studies algebraic structures themselves, not examples ("models") of algebraic structures. For instance, rather than take particular groups as the object of study, in universal algebra one takes "the theory of groups" as an object of study. Varieties From the point of view of universal algebra, an algebra (or algebraic structure ) 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 ) can be represented simply as 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

Extractions: Currently, the entry I've created for Yde Venema is likely to be deleted on the grounds that it's an insignificant biographical entries. Thoughts? jtvisona 03:13, 7 Aug 2003 (UTC) It seems to me that this article deals with algebras in the sense of universal algebras ( algebraic structures ) rather than universal algebra as a branch of mathematics. I think that the current content should be merged with the content of the article algebraic structure . The article about the branch of mathematics should not define and describe algebraic structures but present the history of the branch and its important results, and its title perhaps should be "Theory of universal algebras" to avoid confusion. Andres 08:33, 12 Apr 2004 (UTC) Disagree. History can be added to the page, but the suggested merge isn't an improvement, in my opinion. Charles Matthews 11:25, 12 Apr 2004 (UTC) Let me explain this again. There are different concepts, such as group and group theory or topological space and topology . Analogously, universal algebra aka algebra aka algebraic structure is different concept from universal algebra as a branch of mathematics, and therefore I think they deserve different articles. Currently, in the present article most talk is about universal algebra

Extractions: Universal Algebra heralded as ". . . the standard reference in a field notorious for the lack of standardization . . .", has become the most authoritative, consistently relied on text in a field with applications in other branches of algebra and other fields such as combinatorics, geometry, and computer science. Each chapter is followed by an extensive list of exercises and problems. The "state of the art" account also includes new appendices (with contributions from B. JĂłnsson, R. Quackenbush, W. Taylor, and G. Wenzel) and a well selected additional bibliography of over 1250 papers and books which makes this an indispensable new edition for students, faculty, and workers in the field. "In this reviewer's opinion [the author] has more than succeeded in his aim. The problems at the end of each chapter are well-chosen; there are more than 650 of them. The book is especially suitable for self-study, as the author frequently provides ample explanation not only of what he is proving, but also of how and why he is proving it. As a reference work for the specialist or a text for the student, the book is highly recommended."

Extractions: From Wikipedia, the free encyclopedia Jump to: navigation search In universal algebra a basis is a structure inside of some (universal) algebras, which are called free algebras . It generates all algebra elements from its own elements by the algebra operations in an independent manner. It also represents the endomorphisms of an algebra by certain indexings of algebra elements, which can correspond to the usual matrices when the free algebra is a vector space Examples ... The basis (or reference frame of a (universal) algebra is a function b that takes some algebra elements as values b i and satisfies either one of the following two equivalent conditions. Here, the set of all b i is called basis set , whereas several authors call it the "basis". The set I of its arguments i is called dimension set . Any function, with all its arguments in the whole I , that takes algebra elements as values (even outside the basis set) will be denoted by m . Then
