he present book is based on lectures given by the author at the University of Tokyo during the past ten years. It is intended as a textbook to be studied by students on their own or to be used in a course on Functional Analysis, i.e., the general theory of linear operators infunction spaces together with salient features of its application to diverse fields of modem and classical analysis. Necessary prerequisites for the reading of this book are summarized,with or without proof, in Chapter 0 under titles: Set Theory, Topological Spaces, Measure Spaces and Linear Spaces. Then, starting with the chapter on Semi-norms, a general theory of Banach and Hilbert spaces is presented in connection with the theory of generalized functions of S. L. SOBOLEV and L. SCHWARTZ. While the book is primarily addressed to graduate students, it is hoped it might prove useful to research mathematicians, both pure and applied. The reader may pass, e.g., fromChapter IX (Analytical Theory. of Semi-groups) directly to Chapter XIII (Ergodic Theory and Diffusion Theory) and to Chapter XIV (Integration of the Equation of Evolution). Such materials as "Weak Topologies and Duality in Locally Convex Spaces" and "Nuclear Spaces" are presented in the form of the appendices to Chapter V and Chapter X,respectively. These might be skipped for the first reading by those who are interested rather in the application of linear operators.

Provides avenues for applying functional analysis to the practical study of natural sciences as well as mathematics. Contains worked problems on Hilbert space theory and on Banach spaces and emphasizes concepts, principles, methods and major applications of functional analysis.

《实变函数论与泛函分析:上册•第2版修订本》内容简介：本版保持了初版的思想体系和基本结构，从局部来看作了一定程度的修改。在编写初版时，我们对《实变函数论与泛函分析:上册•第2版修订本》编写的思想体系和基本结构给予了较多的考虑。但由于某些内容过去就很少有作为基础课讲授的教学经验，另一方面也由于当时编写时间比较仓促，因此从具体内容处理的技术方面来看，确有必要进行一次较全面的、细致的修订。本次修订，是在作者对初版进行了两次教学实践和兄弟院校使用初版后提出意见的基础上进行的。

这是一部泛函分析教材。它系统地介绍线性泛函分析的基础知识。全书共分四章： 度量空间；线性算子与线性泛函；广义函数与Coболев空间；以及紧算子与Fredholm算子。《泛函分析讲义(上)》的主要特点是它侧重于分析若干基本概念和重要理论的来源和背景，强调培养读者运用泛函方法解决问题的能力，注意介绍泛函分析理论与数学其它分支的联系。书中包含丰富的例子与应用，对于掌握基础理论有很大帮助。此书适用于理工科大学本科生与研究生阅读，并且可供一般的数学工作者、物理工作者、工程技术人员参考。为便于读者学习，本次重印书末增加了习题补充提示和索引，以供读者参考。

《函数论与泛函分析初步(第7版)》是世界著名数学家A.H.柯尔莫戈洛夫院士在莫斯科大学数学力学系多年讲授泛函分析教程(曾称《数学分析Ⅲ》)的基础上编写的。《函数论与泛函分析初步(第7版)》是关于泛函分析与实变函数论的精细问题的严格的系统阐述，书中反映了作者的教育思想，体现了作者丰富的教学经验与方法。内容包括：集合论初步，度量空间与拓扑空间，赋范线性空间与线性拓扑空间，线性泛函与线性算子，测度、可测函数、积分，勒贝格不定积分、微分论，可和函数空间，三角函数傅里叶变换，线性积分方程，线性空间微分学概要以及附录的巴拿赫代数。 《函数论与泛函分析初步(第7版)》适合数学、物理及相关专业的高年级本科生、研究生、高校教师和研究人员参考使用。

《泛函分析》(原书第2版)是泛函数分析的经典教材，作为Rudin的分析学经典著作之一，《泛函分析》(原书第2版)秉承了内容精练、结构清晰的特点。第2版新增的内容有Kakutani不动点定理，Lamonosov不变子空间定理以及遍历定理等，另外，还适当增加了一些例子和习题。
