In Mathematics the lagebra is represented by an n -tple which lists the parameters defining the particular algebra. The Integers for example with the operations of addition and subtraction with unit is said to be a group ( Integer, +, 0, -). Conventionally similar names are given to the set of ntples: GROUP and to the Set itself: ( Integers in Group ). This network of propositions ( ALGEBRA ), formalizes the relationship between the documentation of an algebra, the name of the set of ntples, and the type of the objects that fit the algebra.

Wiki: Universal algebra 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. Contents: 1. Basic idea 2. Varieties 3.

Home ABUSE FORM Short Reason: Universal Algebra Posted By : Date : Comments : George Grätzer “Universal Algebra" 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. Jónsson, 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. "This book will certainly be, in the years to come, the basic reference to the subject." - The American Mathematical Monthly (First Edition) "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."
