Abstract Algebra

Concrete Abstract Algebra develops the theory of abstract algebra from numbers to Gr"obner bases, while takin in all the usual material of a traditional introductory course. In addition, there is a rich supply of topics such as cryptography, factoring algorithms for integers, quadratic residues, finite fields, factoring algorithms for polynomials, and systems of non-linear equations. A special feature is that Gr"obner bases do not appear as an isolated example. They are fully integrated as a subject that can be successfully taught in an undergraduate context. Lauritzen's approach to teaching abstract algebra is based on an extensive use of examples, applications, and exercises. The basic philosophy is that inspiring, non-trivial applications, and exercises. The basic philosophy is that inspiring, non-trivial applications and examples give motivation and ease the learning of abstract concepts. This book is built on several years of experienced teaching introductory abstract algebra at Aarhus, where the emphasis on concrete and inspiring examples has improved student performance significantly.

An easy-to-use, self-study guide to abstract algebra and its applications. Groups, rings, and fields are fast becoming vital in a wide range of applications utilizing mathematical models in computer science, physics, chemistry, and engineering. This new edition of a proven text offers systematic, concise, easy-to-understand explanations for these basic structures of abstract algebra suitable for self-study. Revised and refined to be accessible even to readers with only rudimentary college algebra, the Second Edition carefully balances coverage of groups, rings, and fields and uses real-world problems to illustrate the theory. Concrete examples such as number theory, integers modulo n, and permutations are introduced at the outset, providing readers with a springboard to computations and subsequent abstract concepts. An ideal resource for scientists and engineers as well as students preparing for the algebra qualifying examinations, "Introduction to Abstract Algebra, Second Edition" presents an exciting array of features, including: Applications to cryptography, coding, geometrical constructions, and Polya counting techniques. Special topics such as symmetric polynomials, nilpotent groups, and finite-dimensional algebras. Nearly 500 solved examples along with hundreds of exercises. Biographies of 13 mathematicians plus historical notes. Review of the necessary background material.

Abstract algebra - Abstract algebra is the field of mathematics concerned with the study of algebraic structures such as groups, rings, fields, modules, vector spaces, and algebras. Many of these structures were defined formally in the nineteenth century, and, indeed, the study of abstract algebra was motivated by the need for more rigor in mathematics.

Derivation (abstract algebra) - In abstract algebra, a derivation on an algebra A over a ring or a field k is a linear map

(Strictly, the universal property approach was invoked; this is somewhat more general than category theory, and the relationship between the two as alternate ways was also being clarified, at the same time.)

This comprehensive treatment of abstract algebra as well as numerous figures, tables, photographs, charts, biographies, computer exercises, and suggested readings that give the subject a current feel and makes the content interesting and relevant for students.
