The main purpose of this second edition is essentially the same as the ?rst edition with changes noted below.
Accordingly, ?rst we quote from the preface by Murray R. Spiegel in the ?rst edition of this text.
“The theory of functions of a complex variable, also called for brevity complex variables or complex
analysis, is one of the beautiful as well as useful branches of mathematics. Although originating in an
atmosphere of mystery, suspicion and distrust, as evidenced by the terms imaginary and complex
present in the literature, it was ?nally placed on a sound foundation in the 19th century through the
efforts of Cauchy, Riemann, Weierstrass, Gauss, and other great mathematicians.”
“This book is designed for use as a supplement to all current standards texts or as a textbook for a formal
course in complex variable theory and applications. It should also be of considerable value to those taking
courses in mathematics, physics, aerodynamics, elasticity, and many other ?elds of science and
“Each chapter begins with a clear statement of pertinent de?nitions, principles and theorems together
with illustrative and other descriptive material. This is followed by graded sets of solved and supplementary
problems. ... Numerous proofs of theorems and derivations of formulas are included among the solved pro-
blems. The large number of supplementary problems with answers serve as complete review of the material
of each chapter.”
“Topics covered include the algebra and geometry of complex numbers, complex differential and inte-
gral calculus, in?nite series including Taylor and Laurent series, the theory of residues with applications to
the evaluation of integrals and series, and conformal mapping with applications drawn from various ?elds.”
“Considerable more material has been included here than can be covered in most ?rst courses. This has
been done to make the book more ?exible, to provide a more useful book of reference and to stimulate
further interest in the topics.”
Some of the changes we have made to the ?rst edition are as follows: (a) We have expanded and cor-
rected many of the sections to make it more accessible for our readers. (b) We have reformatted the
text, such as, the chapter number is now included in the label of all sections, examples, and problems.
(c) Many results are stated formally as Propositions and Theorems.
