Click For Summary

Discussion Overview

The discussion revolves around recommendations for self-study books in complex analysis, addressing various levels of difficulty and intended applications, including engineering and theoretical mathematics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant inquires about a good introductory book for self-study in complex analysis.
  • Another participant suggests "Complex Variables and Applications" by Brown/Churchill, noting its accessibility and suitability for self-study, while mentioning its high price.
  • A different participant recommends Fisher's book for its affordability and quality.
  • One participant shares their positive experience with Ahlfors, highlighting its clarity and intuition, and mentions the relevance of a real analysis background for understanding it.
  • Another participant emphasizes the importance of the intended use of the book, suggesting Kreisig for engineering applications and mentioning that Churchill is also oriented towards engineering.
  • Several titles are proposed for various contexts, including "An Introduction to the Theory of Functions of a Complex Variable" by Copson, and "Complex Analysis" by Stewart and Tall.
  • Participants mention using Lang's book in a course, describing it as decent but not perfect, while also recommending Stein and Shakarchi's book as well as other advanced texts.

Areas of Agreement / Disagreement

Participants express a variety of opinions on the best books for self-study in complex analysis, with no consensus on a single recommended text. Different preferences based on background and intended application are evident.

Contextual Notes

Some recommendations depend on the reader's background in real analysis or specific applications like engineering or fluid mechanics, which may influence the choice of text.

Who May Find This Useful

This discussion may be useful for students and self-learners in mathematics, engineering, and related fields seeking guidance on complex analysis literature.

What is a good introductory book for complex analysis for self study?
 
Physics news on Phys.org
I thought "Complex Variables and Applications" by Brown/Churchill was a fairly good book, although I thought the book was sometimes a little too easy. A lot of problems come with answers and (sometimes an overdose of) hints, so it might be a good book for self study. It is also considered to be a canonical textbook for an undergraduate introductory complex analysis course, so the materials you see on this textbook (mostly chapters 1 through 7) are something you would see in any complex analysis course. The only drawback of this book is the price, so you probably want to get it from your library, or buy a cheaper international edition.
 
Fisher is pretty good, dover printing and it's cheap.
 
I read a chapter or two of Ahlfors when I took real analysis this past year and found the text fairly impressive. It's extremely well-written and Ahlfors gives a lot of intuition, probably because he was an expert in the field. I do remember that you have the real analysis background, so this text would be appropriate. I'm taking complex in the fall, and I'm attempting to at least understand complex integration well over the summer. Our school uses Lang, but I think many previous math majors have recommended Conway over Lang.
 
It depends what you intend to use it for.

A good engineering/applied physics text such as Kreisig contains all you need for this purpose.

Churchill is very engineering oriented.

A classical mathematical introduction can be had from Oxford University

An introduction to the Theory of Functions of a Complex Variable by Copson

A more spicy fully modern treatment is available from Cambridge University

Complex analysis by Stewart and Tall

If you are going to be extending to much Fluid Mechanics the the Alan Jeffrey book

Complex Analysis and Applications is good.
