Abstract algebra From Wikipedia, the free encyclopedia Jump to: navigation search This article is about the branch of mathematics. For the Swedish band, see Abstrakt Algebra Abstract algebra is the subject area of mathematics that studies algebraic structures , such as groups rings fields modules ... vector spaces , and algebras . The phrase abstract algebra was coined at the turn of the 20th century to distinguish this area from what was normally referred to as algebra , the study of the rules for manipulating formulae and algebraic expressions involving unknowns and real or complex numbers , often now called elementary algebra . The distinction is rarely made in more recent writings. Contemporary mathematics and mathematical physics make extensive use of abstract algebra; for example, theoretical physics draws on Lie algebras . Subject areas such as algebraic number theory algebraic topology , and algebraic geometry apply algebraic methods to other areas of mathematics. Representation theory , roughly speaking, takes the 'abstract' out of 'abstract algebra', studying the concrete side of a given structure; see model theory Two mathematical subject areas that study the properties of algebraic structures viewed as a whole are universal algebra and category theory . Algebraic structures, together with the associated

Abstract algebra From Wikipedia, the free encyclopedia Jump to: navigation search Abstract algebra is a part of math which studies algebraic structures . These include: groups Boolean algebra rings vector spaces ... algebras It is normal to build a theory on one kind of structure, like group theory or category theory The purpose of each theory is to organize in a simple-to-complex model the precise definition of a concept, examples, its substructures, the relations between them: morphisms and its applications, inside the own theory as well outside. During history, different fields of mathematics have used algebras . Algebras are about finding or specifying rules on how to calculate with certain mathematical formulas and expressions. Another algebra (which is not abstract ) is elementary algebra , for example. change Examples Solving equations with many variables. This leads to matrices determinants and linear algebra Finding formulas for polynomial equations. This led to the discovery of groups, as an expression of symmetry Quadratic and higher-degree equations and Diophantine equations - espectially when Fermat's last theorem was proved led to the definition of rings, and

Abstract algebra - Definition Abstract algebra is the field of mathematics concerned with the study of algebraic structures such as groups rings and fields . The term "abstract algebra" is used to distinguish the field from " elementary algebra " or "high school algebra" which teaches the correct rules for manipulating formulas and algebraic expressions involving real and complex numbers Historically, algebraic structures usually arose first in some other field of mathematics, were specified axiomatically, and were then studied in their own right in abstract algebra. Because of this, abstract algebra has numerous fruitful connections to all other branches of mathematics. Examples of algebraic structures with a single binary operation are: semigroups monoids quasigroups groups More complicated examples include: rings and fields modules and vector spaces associative algebras and Lie algebras lattices and Boolean algebras In universal algebra , all those definitions and facts are collected that apply to all algebraic structures alike. All the above classes of objects, together with the proper notion of homomorphism , form categories , and category theory frequently provides the formalism for translating between and comparing different algebraic structures.

INTRODUCTION Some of the strengths of this undergraduate/graduate level textbook are the gentle introduction to proof in a concrete setting, the introduction of abstract concepts only after a careful study of important examples, and the gradual increase of the level of sophistication as the student progresses through the book. A number theory thread runs throughout several optional sections, and there is an overview of techniques for computing Galois groups. The book offers an extensive set of exercises that help to build skills in writing proofs. Chapter introductions, together with notes at the ends of certain chapters, provide motivation and historical context, while relating the subject matter to the broader mathematical picture.

ABSTRACT ALGEBRA: A STUDY GUIDE FOR BEGINNERS John A. Beachy Department of Mathematical Sciences Northern Illinois University This study guide is intended for students who are working through the Third Edition of our textbook Abstract Algebra (co-authored with William D. Blair). The guide is focused on solved problems, and my goal is to help students learn how to do proofs, as well as computations. The number of problems can be quite overwhelming, so if you don't have enough time to try all of the solved problems, you can at least read the solutions. The files are in pdf format, suitable for viewing with Adobe Acrobat Reader . Please note that this study guide differs substantially from the Online Study Guide The study guide is currently still under revision. The latest draft 166 pages, pdf format In this draft (posted 3/1/2010), the study guide is very close to final form. There are more than 500 problems, and over half of these problems have full solutions in the study guide. I still hope to add answers for many of the computational problems that do not have solutions. Please send me email if you find typos or mathematical mistakes.

It will be helpful if you have familiarity with the concepts and theorems for groups, because we'll be using many of the same ideas and theorems.

Related subjects: Mathematics Abstract algebra is the subject area of mathematics that studies algebraic structures , such as groups rings, fields, modules, vector spaces , and algebras. Most authors nowadays simply write algebra instead of abstract algebra The term abstract algebra now refers to the study of all algebraic structures, as distinct from the elementary algebra ordinarily taught to children, which teaches the correct rules for manipulating formulas and algebraic expressions involving real and complex numbers , and unknowns. Elementary algebra can be taken as an informal introduction to the structures known as the real field and commutative algebra.
