Solid user-friendly intro book on complex variables, sort of a rough equivalent to linear algebra done right.

I'd highly recommend for a physics or chemistry student who wants a better grasp of residues and conformal mappings, but which is not too mathematically intense.

This is a decent introductory book, geared well toward physicists and engineers but rigorous enough to not offend a math-major. It is clearly written and organized, making it decent as a reference book.

However, it doesn't give much insight into the beauty of the subject. This is a common required textbook for intro courses, so I recommend also getting Visual Complex Analysis as an interesting supplementary text.

There is also a solid free textbook here:

I am familliar with the author's abstract algebra book (which I like), but I have only skimmed parts of this one.

I am familiar with the 5th edition, which I have had for about 20 years. I think it is a reasonable book that covers most of the material many engineers/physicists need for routine applications. By far my favorite sections are those on conformal mapping - the presentation is quite good for applications. In most ways Churchill and Brown is better than the book I had to buy for my complex analysis class (introduction to complex analysis, by Priestley), but I am not wild about the organization of most of the book. Overall I prefer the book by Saff and Snider for an introduction.

I studied the first ten chapters of this book (omitting the final chapters on applications). I used the seventh edition (the eighth edition is now the most current one). I found this text to be ideal for someone (such as myself) who had studied complex analysis a long time ago and wanted to relearn it. The text is almost entirely free of typos and errors, which I find to be important for self-study. The proofs are clear and the examples well-chosen. The exercises are primarily calculations, with a few simple proofs thrown in. This is not a criticism; I found some of the calculations to be challenging. Someone who wants to study more advanced topics in Complex Analysis should consult a second book, such as Lang, Ahlfors or Conway (after studying this text).
