内容简介

　　More precisely， by （i）， I mean a systematic presentation of the materialgoverned by the desire for mathematical perfection and completeness ofthe results. In contrast to （i）， approach （ii） starts out from the question"What are the most important applications？" and then tries to answer thisquestion as quickly as possible. Here， one walks directly on the main roadand does not wander into all the nice and interesting side roads.
　　The present book is based on the second approach. It is addressed toundergraduate and beginning graduate students of mathematics， physics，and engineering who want to learn how functional analysis elegantly solvesma~hematical problems that are related to our real world azld that haveplayed an important role in the history of mathematics. The reader shouldsense that the theory is being developed， not simply for its own sake， butfor the effective solution of concrete problems.

由于泛函分析源自研究各种函数空间，在函数空间里函数列的收敛有不同的类型（譬如逐点收敛，一致收敛，弱收敛等等），这说明函数空间里有不同的拓扑。而函数空间一般是无穷维线性空间。所以抽象的泛函分析研究的是一般的（无穷维的）带有一定拓扑的线性空间。

这是最常见，应用最广的一类拓扑线性空间。比如有限闭区间上的连续函数空间，有限闭区间上的k次可微函数空间。或者对于每个实数p，如果p ≥ 1，一个巴拿赫空间的例子是“所有绝对值的p次方的积分收敛的勒贝格可测函数”所构成的空间。（参看Lp空间）

微分的概念可以在巴拿赫空间中得到推广，微分算子作用于其上的所有函数，一个函数在给定点的微分是一个连续线性映射。

泛函分析是20世纪30年代形成的数学分科，是从变分问题，积分方程和理论物理的研究中发展起来的。它综合运用函数论，几何学，现代数学的观点来研究无限维向量空间上的泛函，算子和极限理论。它可以看作无限维向量空间的解析几何及数学分析。泛函分析在数学物理方程，概率论，计算数学等分科中都有应用，也是研究具有无限个自由度的物理系统的数学工具。
