Author: Ian Stewart, David Tall
First published in 1979 and written by two distinguished mathematicians with a special gift for exposition, this book is now available in a completely revised third edition. It reflects the exciting developments in number theory during the past two decades that culminated in the proof of Fermat’s Last Theorem. Intended as a upper level textbook, it is also eminently suited as a text for self-study.
