This book is written to be a convenient reference for the working
scientist, student, or engineer who needs to know and use basic concepts
in complex analysis. It is not a book of mathematical theory. It is
instead a book of mathematical practice. All the basic ideas of complex
analysis, as well as many typical applica- tions, are treated. Since we
are not developing theory and proofs, we have not been obliged to
conform to a strict logical ordering of topics. Instead, topics have
been organized for ease of reference, so that cognate topics appear in
one place. Required background for reading the text is minimal: a good
ground- ing in (real variable) calculus will suffice. However, the
reader who gets maximum utility from the book will be that reader who
has had a course in complex analysis at some time in his life. This book
is a handy com- pendium of all basic facts about complex variable
theory. But it is not a textbook, and a person would be hard put to
endeavor to learn the subject by reading this book.
