2. Abstract Algebra - Wikipedia, The Free Encyclopedia abstract algebra is the subject area of mathematics that studies algebraic structures, such as groups, rings, fields, modules, vector spaces, and algebras. http://en.wikipedia.org/wiki/Abstract_algebra

Abstract algebra From Wikipedia, the free encyclopedia Jump to: navigation search This article is about the branch of mathematics. For other uses of the term "algebra", see Algebra (disambiguation) . 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 . 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 Contemporary mathematics and mathematical physics make intensive 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.

These notes (with exercises and index) were specifically designed by me for this two-quarter sequence. We will start at the beginning of the Notes, and go approximately halfway through in 5245. The precise pace will depend on the class, and content of each quiz and homework assignment will be indicated as we go. Starred sections and starred exercises are optional. There will be 20-minute quizzes each Tuesday and Thursday in the first hour of class. These quizzes will be open-book, open-notes. The one-hour final (Tues, July 21 for 5245, Wed Aug 26 for 5246) is also open-book, open-notes. email is by far the best way to reach me and get a helpful response: If we have a grader, corresponding homework will be collected after each quiz, and will count for 10 percent of your grade. The lowest two quiz scores will be dropped (but no make-up quizzes given), and quizzes count for 60 percent. The final will be 30 percent. (If there is no homework grader, the quizzes will be 2/3 and the final 1/3). Office hours will be MWF after class, or by arrangement. I respond to

7. Abstract Algebra abstract algebra deals with many structures other than groups. What happens if we two operations called addition and multiplication that behave in ways http://www.math.uchicago.edu/~mileti/museum/algebra.html

Abstract Algebra Most people believe that the mathematics they learn in high school and in their early college years represents the essence of abstraction. What could be less tangible that the idealistic abstract notion of number? Mathematicians work with and delight in bizarre numbers such as i (the square root of -1) which to the uninitiated must seem like an irrational mix of mysticism and numerology. Nonetheless, the basic operations in arithmetic (addition, multiplication, etc.) apply remarkably well to many disparate real-life situations whether you are balancing your checkbook, keeping score in a game of cards, calculating the position of an object under the influence of gravity in physics, or measuring ingrediants for a recipe. In all these situations, the usual grade-school manner in which you add and multiply numbers models the situation perfectly. However, there are times when the normal rules of arithmetic that you learn in grade school do not seem to apply. For example, suppose that you are compiling baseball statistics. To determine a player's batting average, you need to know both the number of hits that he has and the number of times he has been at-bat. If a player has 7 hits in 23 attempts, a natural way to record this information is using the fraction 7/23. (The way this is usually displayed when you are watching a game is the corresponding decimal, truncated to 3 places. In the case of 7 hits in 23 at-bats, it would be written as .304. Although the number .304 is more visually appealing and and conveys information more quickly (the batter gets a hit about 30.4% of the time), it is less precise because we are unable to determine whether the play has 7 hits in 23 at-bats, 14 hits in 46 at-bats, or 70 hits in 230 at-bats.)

Renze Abstract Algebra Abstract algebra is the set of advanced topics of algebra that deal with abstract algebraic structures rather than the usual number systems. The most important of these structures are groups rings , and fields . Important branches of abstract algebra are commutative algebra representation theory , and homological algebra Linear algebra , elementary number theory , and discrete mathematics are sometimes considered branches of abstract algebra. Ash (1998) includes the following areas in his definition of abstract algebra: logic and foundations, counting, elementary number theory , informal set theory linear algebra , and the theory of linear operators SEE ALSO: Arithmetic Algebra Commutative Algebra Discrete Mathematics ...

(ii) Associativity For all a,b,c G, we have a (b c) = (a b) c. (iii) Identity There exists an identity element e G such that e a=a and a e=a for all a G. (iv) Inverses : For each a G there exists an inverse element a G such that a a =e and a a=e. We will usually simply write ab for the product a b. Ring Let R be a set on which two binary operations are defined, called addition and multiplication, and denoted by + and . Then R is called a commutative ring with respect to these operations if the following properties hold: (i) Closure: If a,b

Course Notes It was a compulsion for Artin to present each argument in its purest form, to replace computation by conceptual arguments, to strip the theory of unnecessary ballast. What was the decisive point for him was to show the beauty of the subject to the reader. He himself has said: " We all believe that mathematics is an art. The author of a book, the lecturer in a classroom tries to convey the structural beauty of mathematics to his readers, to his listeners. In this attempt, he must always fail. " Richard Brauer, BAMS 73 (1967), p38. These are full notes for all the advanced (graduate-level) courses I have taught since 1986. Some of the notes give complete proofs (Group Theory, Fields and Galois Theory, Algebraic Number Theory, Class Field Theory, Algebraic Geometry), while others are more in the nature of introductory overviews to a topic. At last count, the notes included about 1700 pages. Errata: This is a list of errors and additional comments not yet incorporated into the files on the web, mainly contributed by readers. The following table indicates how advanced a course is (first, second, or third year graduate course in North American universities), and which courses are prerequisites for it (or would be useful).

In this book David Joyner, Richard Kreminski, and Joann Turisco introduce a wide range of abstract algebra with relevant and interesting applications, from error-correcting codes to cryptography to the group theory of Rubik's cube. They cover basic topics such as the Euclidean algorithm, encryption, and permutations. Hamming codes and Reed-Solomon codes used on today's CDs are also discussed. The authors present examples as diverse as "Rotation," available on the Nokia 7160 cell phone, bell ringing, and the game of NIM. In place of the standard treatment of group theory, which emphasizes the classification of groups, the authors highlight examples and computations. Cyclic groups, the general linear group GL n ), and the symmetric groups are emphasized. With its clear writing style and wealth of examples
