Galois Theory, Fourth Edition

<P>Since 1973, <STRONG>Galois Theory</STRONG> has been educating undergraduate students on Galois groups and classical Galois theory. In <STRONG>Galois Theory, Fourth Edition</STRONG>, mathematician and popular science author Ian Stewart updates this well-established textbook for today’s algebra students. </P> <P><STRONG>New to the Fourth Edition</STRONG></P> <UL> <LI>The replacement of the topological proof of the fundamental theorem of algebra with a simple and plausible result from point-set topology and estimates that will be familiar to anyone who has taken a first course in analysis</LI> <LI>Revised chapter on ruler-and-compass constructions that results in a more elegant theory and simpler proofs</LI> <LI>A section on constructions using an angle-trisector since it is an intriguing and direct application of the methods developed</LI> <LI>A new chapter that takes a retrospective look at what Galois actually did compared to what many assume he did</LI> <LI>Updated references</LI></UL> <P></P> <P>This bestseller continues to deliver a rigorous yet engaging treatment of the subject while keeping pace with current educational requirements. More than 200 exercises and a wealth of historical notes augment the proofs, formulas, and theorems.</P>
