Re: Complex Analysis

i love this book, but it was mostly too hard for my undergraduate class. it begins with a discussion pif formal and convergent powers dries, as does the book of cartan, which may be more accessible, and has excellent chapters near the end on isomorphisms of the complex plane and extended plane. highly recommended but may not be a good first book. for that i prefer the out of print book of frederick green leaf.
