The text covers a broad spectrum between basic and advanced complex variables on the one hand and between theoretical and applied or computational material on the other hand. With careful selection of the emphasis put on the various sections, examples, and exercises, the book can be used in a one- or two-semester course for undergraduate mathematics majors, a one-semester course for engineering or physics majors, or a one-semester course for first-year mathematics graduate students. It has been tested in all three settings at the University of Utah.

The exposition is clear, concise, and lively. There is a clean and modern approach to Cauchy's theorems and Taylor series expansions, with rigorous proofs but no long and tedious arguments. This is followed by the rich harvest of easy consequences of the existence of power series expansions.

Through the central portion of the text, there is a careful and extensive treatment of residue theory and its application to computation of integrals, conformal mapping and its applications to applied problems, analytic continuation, and the proofs of the Picard theorems.

Chapter 8 covers material on infinite products and zeroes of entire functions. This leads to the final chapter which is devoted to the Riemann zeta function, the Riemann Hypothesis, and a proof of the Prime Number Theorem.

Readership

Undergraduate and graduate students interested in complex analysis (one variable).

Reviews

"[This] book presents topics in a logical way that allows the reader to build their intuition about the subject. [For] example, the elementary functions are defined in the first chapter. The first chapter then provides the reader with applications of the rectangular and polar coordinate forms of complex numbers and with examples to understand the properties of analytic and meromorphic functions developed in the subsequent chapters. The proofs of the major theorems follow the same logical and intuitive approach. The exercises are thoughtful and yet accessible to anyone with a sound understanding of multivariable calculus. This is an excellent book."
