算子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。本書覆蓋了算子理論的中心課題,敘述清晰簡潔,讀者很容易與Conway的寫作產生互動。本書前幾章介紹和回顧了C*-代數、正規算子、緊算子和非正規算子,主題包含譜理論、泛函演算和Fredholm指標。此外,還論述了算子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vonNeumann代數等。重要結果覆蓋了諸如Sz.-Nagy伸縮定理、Weyl-vonNeumann-Berg定理和vonNeumann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算子子空間。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教授的處理使本書成為一本引人入勝但又相當縝密等
