復變函數及應用
前言
  This book is a revision of the seventh edition, which was published in 2004. Thatedition has served, just as the earlier ones did, as a textbook for a oneterm introductory course in the theory and application of functions of a complex variable.This new edition preserves the basic content and style of the earlier editions, thefirst two of which were written by the late Ruel V. Churchill alone.  The first objective of.the book is to develop those parts of the theory that areprominent in applications of the subject. The second objective is to furnish an introduction to applications of residues and conformal mapping. With regard to residues,special emphasis is given to their use in evaluating real improper integrals, findinginverse Laplace transforms, and locating zeros of functions. As for conformal mapping, considerable attention is paid to its use in solving boundary value problemsthat arise in studies of heat conduction and fluid flow. Hence the book may beconsidered as a companion volume to the authors text "Fourier Series and Boundary Value Problems," where another classical method for solving boundary valueproblems in partial differential equations is developed.  The first nine chapters of this book have for many years formed the basis of athreehour course given each term at The University of Michigan. The classes haveconsisted mainly of seniors and graduate students concentrating in mathematics,engineering, or one of the physical sciences. Before taking the course, the studentshave completed at least a threeterm calculus sequence and a first course in ordinarydifferential equations. Much of the material in the book need not be covered in thelectures and can be left for selfstudy or used for reference. If mapping by elementaryfunctions is desired earlier in the course, one can skip to Chap. 8 immediately afterChap. 3 on elementary functions.
内容概要
本書初版于20世紀40年代,是經典的本科數學教材之一,對復變函數的教學影響深遠,被美國加州理工學院、加州大學伯克利分校、佐治亞理工學院、普度大學、達特茅斯學院、南加州大學等眾多名校采用。    本書闡述了復變函數的理論及應用,還介紹了留數及保形映射理論在物理、流體及熱傳導等邊值問題中的應用。    新版對原有內容進行了重新組織,增加了更現代的示例和應用,更加方便教學。
作者简介
  James Ward Brown密歇根大學迪爾本分校數學系教授,美國數學學會會員。1964年于密歇根大學獲得數學博士學位。他曾經主持研究美國國家自然科學基金項目,獲得過密歇根大學杰出教師獎,並被列入美國名人錄。  Ruel V.Churchill已故密歇根大學知名教授。早在60多年前,就開始編寫一系列經典教材。除本書外,還與James Ward Brown合著《Fourier Series and Boundary Value Problems》。

章节摘录
  The first objective of.the book is to develop those parts of the theory that areprominent in applications of the subject. The second objective is to furnish an intro-duction to applications of residues and conformal mapping. With regard to residues,special emphasis is given to their use in evaluating real improper integrals, findinginverse Laplace transforms, and locating zeros of functions. As for conformal map-ping, considerable attention is paid to its use in solving boundary value problemsthat arise in studies of heat conduction and fluid flow. Hence the book may beconsidered as a companion volume to the authors text "Fourier Series and Bound-ary Value Problems," where another classical method for solving boundary valueproblems in partial differential equations is developed.  The first nine chapters of this book have for many years formed the basis of athree-hour course given each term at The University of Michigan. The classes haveconsisted mainly of seniors and graduate students concentrating in mathematics,engineering, or one of the physical sciences. Before taking the course, the studentshave completed at least a three-term calculus sequence and a first course in ordinarydifferential equations. Much of the material in the book need not be covered in thelectures and can be left for self-study or used for reference.
