An Introduction to the Theory of Numbers by G.H. Hardy and E. M. Wright is found on the reading list of virtually all elementary number theory courses and is widely regarded as the primary and classic text in elementary number theory. Developed under the guidance of D.R. Heath-Brown this Sixth Edition of An Introduction to the Theory of Numbers has been extensively revised and updated to guide today's students through the key milestones and developments in number theory. Updates include a chapter by J.H. Silverman on one of the most important developments in number theory - modular elliptic curves and their role in the proof of Fermat's Last Theorem - a foreword by A. Wiles, and comprehensively updated end-of-chapter notes detailing the key developments in number theory. Suggestions for further reading are also included for the more avid reader The text retains the style and clarity of previous editions making it highly suitable for undergraduates in mathematics from the first year upwards as well as an essential reference for all number theorists.

G．H．Hardy(1877—1947)享有世界聲譽的數學大師，英國分析學派的創始人之一。數學貢獻涉及解析數論、調和分析、函數論等方麵。培養和指導瞭包括印度數學奇纔拉馬努金和我國數學傢華羅庚在內的眾多數學大傢。

E．M．Wright(1906—2005)英國著名數學傢，畢業於牛津大學，曾多年擔任英國名校阿伯丁大學校長，以及Journal of Graph Theory和Zentralblatt fur Mathematik的名譽主編。愛丁堡皇傢學會會士、倫敦數學會會土。主要研究解析數論、圖論等領域。
