复变函数引论

　　曹怀信编著的《复变函数引论(第2版)》简介：For several years, I have been
conducting courses in Complex Analysis, Real Analysis and
Functional Analysis in a so-called “bilingual” way. That is, the
lessons are given with Chinese textbooks, but mainly teached in
English. The main purpose of teaching in this way is to improve the
undergraduate students’ ability to read and write English. Using a
Chinese textbook in such “bilingual” courses is not, however,
useful for training students’ ability of English-thinking.
Consequently, although there are a number of books on complex
analysis in Chinese, in order to meet the requirements of bilingual
teaching, it is necessary to write a textbook on complex analysis
in English for Chinese undergraduate students. This is just the
main aim of compiling the present book.
