内容简介

　　复分析是数学*核心的学科之一，不但自身引人入胜、丰富多彩，而且在多种其他数学学科（纯数学和应用数学）中都非常有用。《单复变函数论（第三版 英文版）》的与众不同之处在于它从多变量实微积分中直接发展出复变量。每一个新概念引进时，它总对应了实分析和微积分中相应的概念，《单复变函数论（第三版 英文版）》配有丰富的例题和习题来印证此点。
　　作者有条不紊地将分析从拓扑中分离出来，从柯西定理的证明中可见一斑。《单复变函数论（第三版 英文版）》分几章讨论专题，如对特殊函数的完整处理、素数定理和Bergman核。作者还处理了Hp空间，以及共形映射边界光滑性的Painleve定理。
　　《单复变函数论（第三版 英文版）》是一本很吸引人且现代的复分析导引，可用作研究生一年级的复分析教材，它反映了作者们作为数学家和写作者的专业素质。

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.
