內容簡介
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.

總的來說,它們的證明簡潔和邏輯但需要一些耐心跟隨。當做齣一個論點,作者經常引用前題一個b。c和定理x y。沒有顯式地聲明校長z,他們正在使用,即使它可能有一個名字。因此,作為一個讀者,你要麼必須願意遵循麵包屑他們提供或確保你明白為什麼他們的論證工作。這真的不是一個批評,隻是一個觀察。因為這個原因雖然,如果你打算買捲的工作,您N必須買捲N - 1。在每一捲,作者承認的序言中,他們的是太多的材料覆蓋在一個學期;事實上,至少有足夠的材料在每個捲為一個學年工作的價值。

Hilbert space當然可以是有限維的,但是有限維的不很好玩。以為哪怕隻是一個topological vector space (over C or R) (就是一個嚮量空間和一個拓撲,而這個拓撲使得嚮量空間上的兩種運算連續),如果是有限維,那也和C^n或R^n是一樣的。(homeomorphic)

人都是有局限性的,「提升自我」這件事不隻是技能上的提升,更核心的是視野、理念、思維方式這些意識世界裏的東西。「讀史使人明智,讀詩使人靈秀,數學使人周密,科學使人深刻,倫理學使人莊重,邏輯修辭之學使人善辯:凡有所學,皆成性格。」第

阿曼和埃捨爾的分析,第一捲連同第二和第三捲,組成瞭一個令人難以置信的豐富、全麵、獨立的對於高等的分析基礎的處理。從集閤論和實數的構建,作者繼續引理、定理,定理證明的聲明和斯托剋的定理在最後一章的流形體積三世。

注意Hilbert space一定是Banach space,而Hilbert space 和 Banach space都是特殊的topological vector space。的確,所以老一點的書都直接定義Hilbert space是l^2,因為那時都假設有一個可數的orthonormal basis。看謝惠民吧,那個什麼多維騎還是放一邊。不過答案隻有提示,很多答案可以在薛春華中找我看一本數學書大概三百頁厚,半個月看不完啊,一天也就看兩三頁,看得時間也不多,就兩三個鍾,還消化不良,有時候想趕快看越快看越學得少與不懂。你們都是怎麼看書的,來跟大傢分享下吧!

比如我們10歲以前,阿拉丁神燈這一類兒童書籍能夠打動我們,也能夠讓我們開始學著認識這個世界。然而當我們長大一些之後,能夠打動我們或者對我們有巨大幫助的書籍,會變化。所以第一個建議是:根據自己當前的人生階段、認知水平來思考自己應該看哪一類書,比如說初入職場的人,去學習具體的工作技能(如Excel的使用)會比研讀管理學理論要更為有益,因為對於這個階段的你來說,技能性的東西可以現學現練,很快就能把書裏的東西轉化為自己能力的一部分。
