Explore the main algebraic structures and number systems thatplay a central role across the field of mathematics

Algebra and number theory are two powerful branches of modernmathematics at the forefront of current mathematical research, andeach plays an increasingly significant role in different branchesof mathematics, from geometry and topology to computing andcommunications. Based on the authors' extensive experience withinthe field, Algebra and Number Theory has an innovativeapproach that integrates three disciplines?linear algebra,abstract algebra, and number theory?into one comprehensiveand fluid presentation, facilitating a deeper understanding of thetopic and improving readers' retention of the main concepts.

The book begins with an introduction to the elements of settheory. Next, the authors discuss matrices, determinants, andelements of field theory, including preliminary information relatedto integers and complex numbers. Subsequent chapters explore keyideas relating to linear algebra such as vector spaces, linearmapping, and bilinear forms. The book explores the development ofthe main ideas of algebraic structures and concludes withapplications of algebraic ideas to number theory.

Interesting applications are provided throughout to demonstratethe relevance of the discussed concepts. In addition, chapterexercises allow readers to test their comprehension of thepresented material.

Algebra and Number Theory is an excellent book forcourses on linear algebra, abstract algebra, and number theory atthe upper-undergraduate level. It is also a valuable reference forresearchers working in different fields of mathematics, computerscience, and engineering as well as for individuals preparing for acareer in mathematics education.

Choice Review

The title of this work may be misleading; it is designed to integrate topics in algebra, linear algebra, and elementary number theory. As such, its appeal is the integration. There are dedicated books in each area that are better, but there are virtually none that integrate the three. Dixon (Univ. of Alabama, Tuscaloosa), Kurdachenko (Dnepropetrovsk National Univ., Ukraine), and Subbotin (National Univ., California) write well and include ample, appropriate examples and exercises. Viewing this book as an integrated resource, it would be difficult to pick and choose topics for a course. The first six chapters are devoted mainly to linear algebra. The remaining chapters are "Rings," "Groups," "Arithmetic Properties of Rings" (elementary number theory in a commutative ring setting), and "The Real Number System." The book is aimed at students bound for graduate work in mathematics, so the intended audience is a talented group. It would be an ambitious one-year course for "normal" undergraduates; falling short of completion, it misses some key topics--an inherent risk of an integrated program. However, instructors contemplating such a unified approach should give this book serious consideration. Summing Up; Recommended. Upper-division undergraduates through researchers/faculty. J. R.
