Now in its fourth edition, the first part of this book is devoted to the
basic material of complex analysis, while the second covers many special
topics, such as the Riemann Mapping Theorem, the gamma function, and
analytic continuation. Power series methods are used more systematically
than is found in other texts, and the resulting proofs often shed more
light on the results than the standard proofs. While the first part is
suitable for an introductory course at undergraduate level, the
additional topics covered in the second part give the instructor of a
gradute course a great deal of flexibility in structuring a more
advanced course.
