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.

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

這種方法最初要求更多的讀者和他的抽象能力,但在評審者的意見,是絕對的最好方法主體。我真的不知道什麼是真正的初學者在數學也能想齣來但替代方法是定義事物反復在越來越通用上下文最分析文本做。

這套書給人的感覺有點不上不下。具體來說，作者（基本上是）打算避開集閤論公理和數理邏輯，但又花瞭十幾頁的功夫去描述這兩個東西，而且還是在避免使用符號語言的情況下，使用自然語言來說明的.......嘛，因為原文是德文，說明上應該會比這英譯本的要嚴格一些，但是這英譯本就......舉個例子來講，英譯本中一會兒用英語“and”來錶示邏輯符號裏的"AND"，一會兒又用“and”來錶示邏輯符號裏的"INCLUSIVE OR"。都無語瞭......

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。
