內容簡介

　　《華章數學原版精品係列：復變函數及應用（英文版·第9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。這本經典的教材對復變函數的教學影響深遠，被美國斯坦福大學、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。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，密歇根大學迪爾伯恩分校數學係榮休教授，美國數學會會士，入編《美國名人錄》和《世界名人錄》。1964年於密歇根大學獲得博士學位，1971年至2011年任密歇根大學教授，並於 1976年獲得密歇根大學傑齣教學奬。



Ruel V. Churchill(1899—1987 )生前是密歇根大學知名教授，於芝加哥大學取得理學學士學位，於密歇根大學取得物理學碩士及數學博士學位，自1922年起在密歇根大學執教。他從20世紀40年代開始 編寫一係列經典教材，除本書外，還與James Ward Rrown閤著有《Fourier Series and Boundary Value Problems》。
