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.

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。

導數不齣現,直到301頁,但當它介紹,它定義在條款的這東西到底是什麼:一個綫性近似。在大多數文本,這個觀點並不是討論直到“多元”分析覆蓋。

值得數學係本科生,研究生看看,是一本好書!
