Masse R. Complex Variables 6ed 2022

Textbook in PDF format

Complex variable theory constitutes a very elegant and extremely useful branch of mathematics. The range of applications of complex variables in the sciences, engineering, and mathematics is broad and far-reaching. The use of complex variable theory in studying functions arising from physical problems often leads to a deeper insight into the general properties of these functions.
The material in this book is organized and presented in a manner designed to provide a comprehensive first look at complex variable theory. Most of the sources for this book are
