Abstract Algebra: Theory and Applications
by Thomas Judson
Publisher: Virginia Commonwealth University Mathematics 2009
Number of pages: 428
This text is intended for a one- or two-semester undergraduate course in abstract algebra and covers the traditional theoretical aspects of groups, rings, and fields. Many applications are included, including coding theory and cryptography. The nature of the exercises ranges over several categories; computational, conceptual, and theoretical problems are included.
