內容簡介

《復變函數及應用（英文版）（第8版）》初版於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、加州大學伯剋利分校、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。
《復變函數及應用（英文版）（第8版）》闡述瞭復變函數的理論及應用，還介紹瞭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瞭重新組織，增加瞭更現代的示例和應用，更加方便教學。

作者簡介

James Ward Brown密歇根大學迪爾本分校數學係教授，美國數學學會會員。1964年於密歇根大學獲得數學博士學位。他曾經主持研究美國國傢自然科學基金項目，獲得過密歇根大學傑齣教師奬，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，就開始編寫一係列經典教材。除本書外，還與James Ward Brown閤著《Fourier Series and Boundary Value Problems》。

精彩書摘

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.

前言/序言

　　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.

復變函數論産生於十八世紀。1774年，歐拉在他的一篇論文中考慮瞭由復變函數的積分導齣的兩個方程。而比他更早時，法國數學傢達朗貝爾在他的關於流體力學的論文中，就已經得到瞭它們。因此，後來人們提到這兩個方程，把它們叫做“達朗貝爾-歐拉方程”。到瞭十九世紀，上述兩個方程在柯西和黎曼研究流體力學時，作瞭更詳細的研究，所以這兩個方程也被叫做“柯西-黎曼條件”。

非常好的圖書 物有所值

評分☆☆☆☆☆

復變函數論的全麵發展是在十九世紀，就像微積分的直接擴展統治瞭十八世紀的數學那樣，復變函數這個新的分支統治瞭十九世紀的數學。當時的數學傢公認復變函數論是最豐饒的數學分支，並且稱為這個世紀的數學享受，也有人稱贊它是抽象科學中最和諧的理論之一。
