Galois Theory [PDF ebook] 

Since 1973, Galois theory has been educating undergraduate students on Galois groups and classical Galois theory. In Galois Theory, Fifth Edition , mathematician and popular science author Ian Stewart updates this well-established textbook for today’s algebra students.

New to the Fifth Edition

• Reorganised and revised Chapters 7 and 13


• New exercises and examples


• Expanded, updated references


• Further historical material on figures besides Galois: Omar Khayyam, Vandermonde, Ruffini, and Abel


• A new final chapter discussing other directions in which Galois theory has developed: the inverse Galois problem, differential Galois theory, and a (very) brief introduction to p-adic Galois representations

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.
