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.

這本書覆蓋瞭從入門機械製圖工程師/技師所必需知道的關於産業的知識。書中還覆蓋瞭所必需的進階知識。 《實分析教程(第2版)(英文影印版)》是一部備受專傢好評的教科書，書中用現代的方式清晰論述瞭實分析的概念與理論，定理證明簡明易懂，可讀性強。在第一版的基礎上做瞭全麵修訂，有200道例題，練習題由原來的1200道增加到1300習題。本書的寫法像一部文學讀物，這在數學教科書很少見，因此閱讀本書會是一種享受。

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

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)

Hilbert space（希爾伯特空間）的定義是一個complete的inner product space。LZ所說的空間是l^2，隻是一種Hilbert空間的例子。

值得數學係本科生，研究生看看，是一本好書！

沒有想象中的好，而且太薄瞭

拓撲結構的基本概念如連通性、密實度和介紹瞭homeomorphisms早期使用作為一個基礎,證明將遠不及優雅的(和不直接)否則。例如,介值定理,證明瞭結果的連接的一個空間。一旦這是結果確定下來的普遍性,它討論瞭R。
