内容简介
《An Introduction to Complex Analysis（复分析引论）》是作者多年从事复变函数论双语教学经验的总结. 其内容设置完全适合我国现行高等院校（特别是师范院校）本科教学的教学目标与课时需要.《An Introduction to Complex Analysis（复分析引论）》内容深入浅出、层次分明， 理论体系严谨、逻辑推导详尽， 强调“分析式”教学法， 在引入概念前， 加入了必要的分析与归纳总结， 然后提出相应的概念; 在提出问题之后， 进行推理分析、增加条件， 最后得到问题的答案， 并把前边的讨论总结成一个定理. 其次， 《An Introduction to Complex Analysis（复分析引论）》配有大量图形， 帮助读者直观理解相应的概念与论证思路.
