Introduction to Abstract Algebra

An Introduction to Abstract Algebra

algebra plays a fundamental role in many areas of science and engineering. In this chapter we describe a variety of basic algebraic structures that play roles in the generation and analysis of sequences, especially sequences intended for use in communications and cryptography. This include groups (see Section 1.1), rings (see Section 1.2), and polynomials over rings (see Section 1.4). We also e...

Review of the book: Introduction to Abstract Algebra

The book of Jonathan D. H. Smith, ”Introduction to Abstract Algebra” is a careful treatment of the principal topics of Abstract Algebra in 327 pages. It contains 11 chapters (318 pages) and an index of terms (9 pages). There is no bibliography. Taking a different approach from several books, it helps the reader to have a solid introduction to abstract algebra and establishes the link between it...
