內容簡介
復分析是數學*核心的學科之一,不但自身引人入勝、豐富多彩,而且在多種其他數學學科(純數學和應用數學)中都非常有用。《單復變函數論(第三版 英文版)》的與眾不同之處在於它從多變量實微積分中直接發展齣復變量。每一個新概念引進時,它總對應瞭實分析和微積分中相應的概念,《單復變函數論(第三版 英文版)》配有豐富的例題和習題來印證此點。
作者有條不紊地將分析從拓撲中分離齣來,從柯西定理的證明中可見一斑。《單復變函數論(第三版 英文版)》分幾章討論專題,如對特殊函數的完整處理、素數定理和Bergman核。作者還處理瞭Hp空間,以及共形映射邊界光滑性的Painleve定理。
《單復變函數論(第三版 英文版)》是一本很吸引人且現代的復分析導引,可用作研究生一年級的復分析教材,它反映瞭作者們作為數學傢和寫作者的專業素質。

前言/序言
This third edition follows the overall plan and even the specific arrangement of topics of the second edition, but there have been substantial changes in matters of detail. A considerable number of the proofs, especially in the later chapters, have been corrected, clarified, or simplified. Many of the exercises have been revised, and in many cases the exercises have been rearranged to make for greater consistency and less duplication. The mathematical roads that this new edition follows are the same as before, but we hope that the ride is considerably smoother.
We are indebted to Harold Boas and Gerald B. Folland for their extremely careful reading of the second edition in the course of their using the book as a text. They provided far more suggestions and corrections than we had any right to expect of anyone but ourselves, and to the extent that this edition is superior to the previous, it is very largely to that extent that we are in their debt. Any remaining errors are, of course, our responsibility.
Rahul Fernandez brought mathematical expertise, typesetting skills, and a great deal of patience to the daunting task of taking our heavily marked and indeed sometimes scribbled-upon manuscript of the second edition and making this third one. We are grateful to him for his efforts. We also thank the publishing staff of the American Mathematical Society for their willingness to undertake a third edition and for their support in general.
