內容簡介

　　The first part of this volume is based on a course taught at Princeton　University in 1961-62; at that time, an excellent set of notes was prepared　by David Cantor, and it was originally my intention to make these notes　available to the mathematical public with only quite minor changes. Then, among some old papers of mine, I accidentally came across a long-forgotten manuscript by Chevalley, of pre-war vintage (forgotten, that is to say, both by me and by its author) which, to my taste at least, seemed to have aged very well. It contained a brief but essentially com- plete account of the main features of classfield theory, both local and global; and it soon became obvious that the usefulness of the intended volume would be greatly enhanced if I included such a treatment of this topic. It had to be expanded, in accordance with my own plans, but its outline could be preserved without much change. In fact, I have adhered to it rather closely at some critical points.

前言/序言

　　The first part of this volume is based on a course taught at PrincetonUniversity in 1961-62; at that time， an excellent set of notes was preparedby David Cantor， and it was originally my intention to make these notesavailable to the mathematical public with only quite minor changes.Then， among some old papers of mine， I accidentally came across along=forgotten manuscript by Chevalley， of pre-war vintage （forgotten，that is to say， both by me and by its author） which， to my taste at least，seemed to have aged very well. It contained a brief but essentially com-plete account of the main features of classfield theory， both local andglobal; and it soon became obvious that the usefulness of the intendedvolume would be greatly enhanced if I included such a treatment of thistopic. It had to be expanded， in accordance with my own plans， but itsoutline could be preserved without much change. In fact， I have adheredto it rather closely at some critical points.
　　To improve upon Hecke， in a treatment along classical lines of thetheory of algebrai~ numbers， would be a futile and impossible task. Aswill become apparent from the first pages of this book， I have rathertried to draw the conclusions from the developments of the last thirtyyears， whereby locally compact groups， measure and integration havebeen seen to play an increasingly important role in classical number-theory. In the days of Dirichlet and Hermite， and even of Minkowski，the appeal to "continuous variables" in arithmetical questions may wellhave seemed to come out of some magicians bag of tricks. In retrospect，we see now that the real numbers appear there as one of the infinitelymany completions of the prime field， one which is neither more nor lessinteresting to the arithmetician than its p=adic companions， and thatthere is at least one language and one technique， that of the adeles， for bringing them all together under one roof and making them cooperate for a common purpose. It is needless here to go into the history of thesedevelopments; suffice it to mention such names as Hensel， Hasse， Chevalley， Artin; every one of these， and more recently Iwasawa， Tate， Tamagawa， helped to make some significant step forward along this road. Once the presence of the real field， albeit at infinite distance， ceases to be regarded as a necessary ingredient in the arithmeticians brew.

解析數論的創立當歸功於黎曼。他發現瞭黎曼zeta函數之解析性質與數論中的素數分布問題存在深刻聯係。確切的說， 黎曼ζ函數的非平凡零點的分布情況決定瞭素數的很多性質。黎曼猜測， 那些零點都落在復平麵上實部為1/2的直綫上。這就是著名的黎曼假設--被譽為韆禧年七大世界數學難題之一。值得注意的是， 歐拉實際上在處理素數無限問題時也用到瞭解析方法。
