内容简介
The first one is purely algebraic. Its objective is the classification ofquadratic forms over the field of rational numbers (Hasse-Minkowskitheorem). It is achieved in Chapter IV. The first three chapters contain somepreliminaries: quadratic reciprocity law, p-adic fields, Hilbert symbols.Chapter V applies the preceding results to integral quadratic forms indiscriminant + 1. These forms occur in various questions: modular functions,differential topology, finite groups. The second part (Chapters VI and VII) uses "analytic" methods (holomor-phic functions). Chapter VI gives the proof of the "theorem on arithmeticprogressions" due to Dirichlet; this theorem is used at a critical point in thefirst part (Chapter 111, no. 2.2). Chapter VII deals with modular forms,and in particular, with theta functions. Some of the quadratic forms ofChapter V reappear here.

前言/序言
This book is divided into two parts.
The first one is purely algebraic. Its objective is the classification ofquadratic forms over the field of rational numbers (Hasse-Minkowskitheorem). It is achieved in Chapter IV. The first three chapters contain somepreliminaries: quadratic reciprocity law, p-adic fields, Hilbert symbols.Chapter V applies the preceding results to integral quadratic forms indiscriminant + 1. These forms occur in various questions: modular functions,differential topology, finite groups. The second part (Chapters VI and VII) uses "analytic" methods (holomor-phic functions). Chapter VI gives the proof of the "theorem on arithmeticprogressions" due to Dirichlet; this theorem is used at a critical point in thefirst part (Chapter 111, no. 2.2). Chapter VII deals with modular forms,and in particular, with theta functions. Some of the quadratic forms ofChapter V reappear here.
The two parts correspond to lectures given in 1962 and 1964 to secondyear students at the Ecole Normale Superieure. A redaction of these lecturesin the form of duplicated notes, was made by J.-J. Saosuc (Chapters l-IV)and J.-P. Ramis and G. Ruget (Chapters VI-VIi). They were very useful tome; I extend here my gratitude to their authors.

自然数或正整数的数学理论就是众所周知的算术.至于几何、 代数等许多数学分支学科的名称,都是后来很晚的时候才有的。

算术算术是数学中最古老、最基础和最初等的部分。它研究数的性质及其运算。把数和数的性质、数和数之间的四则运算在应用过程中的经验累积起来,并加以整理,就形成了最古老的一门数学——算术。在古代全部数学就叫做算术,现代的代数学、数论等最初就是由算术发展起来的。后来,算学、数学的概念出现了,它代替了算术的含义,包括了全部数学,算术就变成了一个分支了。算术(arithmetic) 数学的一个基础分支。它以自然数和非负分数为主要对象。算术的内容包括两部分,一部分讨论自然数的读法、写法和它的基本运算,这一部分包括进位制和记数法,主要是十进位制,其他的 进位制与十进位制仅是采用的基数不同,都可以仿照十进位数的原理和原则进行计算,算术的另一部分包括算术运算的方法与原理的应用。如分数与百分数计算,各种量及其计算,比和比例,以及算术应用题。
