內容簡介

　　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.

在巴拿赫空間中，相當部分的研究涉及到對偶空間的概念，即巴拿赫空間上所有連續綫性泛函所構成的空間。對偶空間的對偶空間可能與原空間並不同構，但總可以構造一個從巴拿赫空間到其對偶空間的對偶空間的一個單同態。

由於泛函分析源自研究各種函數空間，在函數空間裏函數列的收斂有不同的類型（譬如逐點收斂，一緻收斂，弱收斂等等），這說明函數空間裏有不同的拓撲。而函數空間一般是無窮維綫性空間。所以抽象的泛函分析研究的是一般的（無窮維的）帶有一定拓撲的綫性空間。

泛函分析是20世紀30年代形成的數學分科，是從變分問題，積分方程和理論物理的研究中發展起來的。它綜閤運用函數論，幾何學，現代數學的觀點來研究無限維嚮量空間上的泛函，算子和極限理論。它可以看作無限維嚮量空間的解析幾何及數學分析。泛函分析在數學物理方程，概率論，計算數學等分科中都有應用，也是研究具有無限個自由度的物理係統的數學工具。
