內容提要

《泛函分析（版）》是美國科學院院士Peter D．Lax在CotJrant數學所長期講授泛函分析課程的教學經驗基礎上編寫的。《泛函分析（版）》括泛函分析的基本內容：Barlach空間、Hilbert空間和綫性拓撲空間的基本概念和性質，綫性拓撲空間中的凸集及其端點集的性質，有界綫性算子的性質等。可作為本科生泛函分析課的教學內容；還括泛函分析較深的內容：自伴算子的譜分解理論。緊算子的理論，交換Barlach代數的Gelfand理論，不變子空間的理論等。可作為研究生泛函分析課的教學內容。《泛函分析（版）》特彆強調泛函分析與其他數學分支的聯係及泛函分析理論的應用，可以使讀者深刻地理解到：抽象的泛函分析理論有著豐富的數學背景。
