    運算元理論在現代數學的許多重要領城諸如泛函分析、微分方程、指標論、表示論、數學物理中充當重要角色。本書覆蓋了運算元理論的中心課題,敘述清晰簡潔,讀者很容易與Conway的寫作產生互動。
    約翰·康韋著的《運算元理論教程(英文版)(精)/美國數學會經典影印系列》前幾章介紹和回顧了C*-代數、正規運算元、緊運算元和非正規運算元,主題包含譜理論、泛函演算和Fredholm指標。此外,還論述了運算元理論和解析函數之間某些深刻的聯繫。後續章節講述了更高級的主題,包括C*-代數的表示、緊微擾和von Neumann代數等。重要結果覆蓋了諸如Sz.-Nagy伸縮定理、Weyl-von Neumann-Berg定理和von Neumann代數的分類,同樣也講述了對Fredholm理論的處理,這些高級論題均處於當今研究的中心。最後一章介紹了自返子空間,即由其不變子空間決定的運算元子空間。這些連同超自返空間是現代非對稱代數研究中成功的插曲之一。
    Conway教授的權威性處理使本書成為一本引人入勝但又相當縝密的教材,適合於已經上過泛函分析標準課程的研究生。
