內容簡介

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.

算術不隻是簡單的計算

評分☆☆☆☆☆

不夠詳細，不夠完善，不夠變化。

評分☆☆☆☆☆

前兩個是加法和乘法的交換律，它說明人們可以交換加法或乘法中元素的次序。第三個是加法的結閤律，它錶明三個數相加時，或者我們把第一個加上第二個與第三個的和；或者我們把第三個加上第一個與第二個的和，其結果都相同。第四個是乘法的結閤律。最後一個是分配律，它錶明用一個整數去乘一個和時，我們可以用這整數去乘這和的每一項，然後把這些乘積加起來。

　　讀者有一定的基本同調代數和代數拓撲知識就可以理解本書。每章末都附有練習，這些可以幫助學生更好的理解書中的知識體係。附錄給齣瞭部分習題的解答。第二版中在內容上做瞭較大的改動，增加瞭80多例子和大量更深層次的內容，如，Cech上同調、Oliver變換、插值理論、廣義流形、局部齊性空間、同調縴維和p進變換群。目次：層和準層；層上同調；與其他上同調定理的比較；譜序列的應用；Borel-Moore同調；上層和ech同調。
