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.

希爾伯特空間可以利用以下結論完全分類，即對於任意兩個希爾伯特空間，若其基的基數相等，則它們必彼此同構。對於有限維希爾伯特空間而言，其上的連續綫性算子即是綫性代數中所研究的綫性變換。對於無窮維希爾伯特空間而言，其上的任何態射均可以分解為可數維度（基的基數為50）上的態射，所以泛函分析主要研究可數維度上的希爾伯特空間及其態射。希爾伯特空間中的一個尚未完全解決的問題是，是否對於每個希爾伯特空間上的算子，都存在一個真不變子空間。該問題在某些特定情況下的答案是肯定的。
