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)享有世界声誉的数学大师，英国分析学派的创始人之一。数学贡献涉及解析数论、调和分析、函数论等方面。培养和指导了包括印度数学奇才拉马努金和我国数学家华罗庚在内的众多数学大家。

E．M．Wright(1906—2005)英国著名数学家，毕业于牛津大学，曾多年担任英国名校阿伯丁大学校长，以及Journal of Graph Theory和Zentralblatt fur Mathematik的名誉主编。爱丁堡皇家学会会士、伦敦数学会会土。主要研究解析数论、图论等领域。
