内容简介

　　The present book strives for clarity and transparency. Right from the begin-ning， it requires from the reader a willingness to deal with abstract concepts， as well as a considerable measure of self-initiative. For these e&，rts， the reader will be richly rewarded in his or her mathematical thinking abilities， and will possess the foundation needed for a deeper penetration into mathematics and its applications.
　　This book is the first volume of a three volume introduction to analysis. It de- veloped from. courses that the authors have taught over the last twenty six years at the Universities of Bochum， Kiel， Zurich， Basel and Kassel. Since we hope that this book will be used also for self-study and supplementary reading， we have included far more material than can be covered in a three semester sequence. This allows us to provide a wide overview of the subject and to present the many beautiful and important applications of the theory. We also demonstrate that mathematics possesses， not only elegance and inner beauty， but also provides efficient methods for the solution of concrete problems.

前言/序言

　　Logical thinking， the analysis of complex relationships， the recognition of under- lying simple structures which are common to a multitude of problems - these are the skills which are needed to do mathematics， and their development is the main goal of mathematics education.
　　Of course， these skills cannot be learned 'in a vacuum'. Only a continuous struggle with concrete problems and a striving for deep understanding leads to success. A good measure of abstraction is needed to allow one to concentrate on the essential， without being distracted by appearances and irrelevancies.
　　The present book strives for clarity and transparency. Right from the begin-ning， it requires from the reader a willingness to deal with abstract concepts， as well as a considerable measure of self-initiative. For these e&，rts， the reader will be richly rewarded in his or her mathematical thinking abilities， and will possess the foundation needed for a deeper penetration into mathematics and its applications.
　　This book is the first volume of a three volume introduction to analysis. It de- veloped from. courses that the authors have taught over the last twenty six years at the Universities of Bochum， Kiel， Zurich， Basel and Kassel. Since we hope that this book will be used also for self-study and supplementary reading， we have included far more material than can be covered in a three semester sequence. This allows us to provide a wide overview of the subject and to present the many beautiful and important applications of the theory. We also demonstrate that mathematics possesses， not only elegance and inner beauty， but also provides efficient methods for the solution of concrete problems.
　　Analysis itself begins in Chapter II. In the first chapter we discuss qLute thor- oughly the construction of number systems and present the fundamentals of linear algebra. This chapter is particularly suited for self-study and provides practice in the logical deduction of theorems from simple hypotheses. Here， the key is to focus on the essential in a given situation， and to avoid making unjustified assumptions.An experienced instructor can easily choose suitable material from this chapter to make up a course， or can use this foundational material as its need arises in the study of later sections.

注意Hilbert space一定是Banach space，而Hilbert space 和 Banach space都是特殊的topological vector space。的确，所以老一点的书都直接定义Hilbert space是l^2，因为那时都假设有一个可数的orthonormal basis。看谢惠民吧，那个什么多维骑还是放一边。不过答案只有提示，很多答案可以在薛春华中找我看一本数学书大概三百页厚，半个月看不完啊，一天也就看两三页，看得时间也不多，就两三个钟，还消化不良，有时候想赶快看越快看越学得少与不懂。你们都是怎么看书的，来跟大家分享下吧!

l^2里面既然是实数数列，其定义便是从N到R的函数，怎么可以是有限呢？否则这函数就不是well-defined的了。

评分☆☆☆☆☆

Hilbert space（希尔伯特空间）的定义是一个complete的inner product space。LZ所说的空间是l^2，只是一种Hilbert空间的例子。

评分☆☆☆☆☆

值得数学系本科生，研究生看看，是一本好书！

评分☆☆☆☆☆

导数不出现,直到301页,但当它介绍,它定义在条款的这东西到底是什么:一个线性近似。在大多数文本,这个观点并不是讨论直到“多元”分析覆盖。

评分☆☆☆☆☆

Hilbert space当然可以是有限维的，但是有限维的不很好玩。以为哪怕只是一个topological vector space (over C or R) （就是一个向量空间和一个拓扑，而这个拓扑使得向量空间上的两种运算连续），如果是有限维，那也和C^n或R^n是一样的。（homeomorphic)

开笔此书前，我曾列过一个写作计划。按人名顺序一个接一个去罗列—他们都是些浪荡江湖，和我的人生轨迹曾交叉重叠的老友们。 　　当时，我坐在一辆咣当咣当的绿皮火车里，天色微亮，周遭是不同省份的呼噜声。我找了个本子，塞着耳机一边听歌一边写……活着的、死了的、不知不觉写满了七八页纸。我吓了一跳，怎么这么多的素材？不过十年，故事却多得堆积如山，这哪里是一本书能够写的完的。 　　头有点儿大，不知该如何取舍，于是索性随手圈了几个老友的人名。反正写谁都是写，就像一大串美味的葡萄，随手摘下的，都是一粒粒饱满的甜。随手圈下的名单，是为此书篇章构成之由来。圈完后一抬头，车窗外没有起伏，亦没有乔木，已是一马平川的华北平原。 　　书的创作过程中，我慢慢梳理出了一些东西，隐约发现自己将推展开的世界，于已经习惯了单一幸福感获取途径的人们而言，那是另一种幸福感。 　　那是一些值得我们去认可、寻觅的幸福感。他们或许是陌生的，但发着光。在我的认知中，一个成熟健全的当代文明社会，理应尊重多元的个体价值观，理应尊重个体幸福感获得方式。这种尊重，应该建立在了解的基础之上，鉴于国人文化传统里对陌生事物的天然抵触因子，“如何去了解”这几个字愈发重要。 　　那么，亲爱的们，我该如何去让你了解那些多元而又陌生的幸福感呢？ 　　写书时，恰逢山东大学抬爱，让我有缘受聘于山东大学儒学高等研究院，于是趁机做了一场名为《亚文化下成长方式的田野调查》的报告讲座。 　　那天会场塞满了人，场面出乎意料的火爆，来的大都是85 后和90后。我讲的就是这份名单：大军、路平、月月、白玛央宗……我和他们的共同生活就是一场田野调查。我没用太学术的语言词汇去贯穿讲座，但讲了许多细节的故事， 那天的叙述方式，是为本书行文的基调。 　　卡尔维诺说：“要把地面上的人看清楚，就要和地面保持距离”。这句话给我带来一个意像：一个穿西服打领带的人，手足并用爬在树上，和大部分同类保持着恰当的距离。他晃荡着腿，骑在自我设定的叛逆里，心无挂碍，乐在其中。偶尔低头看看周遭过客，偶尔抬头，漫天星斗。 　　我期待出到第十本书的时候，也能爬上这样一棵树。 　　当下是我第一本书，芹献诸君后，若价值观和您不重叠、行文有不得人心处，请姑念初犯…… 　　我下次不会改的。 　　等我爬上树了再说。 　　我不敢说这本书写得有多好多好，也懒得妄自菲薄，只知过程中三易其稿，惹得责编戴克莎小姐几度差点儿忿极而泣。如此这般折腾，仅为本色二字：讲故事人的本色，故事中人们的本色。 　　或许，打磨出本色的过程，也是爬树的过程吧。 　　文至笔端心意浅，话到唇畔易虚言，且洒莲实二三子，自有方家识真颜。 　　这本书完稿后，我背起吉他，从北到南，用一个月的时间挨个去探望了书中的老友们，除了那个不用手机的女孩，其他的人我几乎见了一个遍。
