Book Description

Variables and Applications That Are Complicated, A textbook for an introductory course in the theory and application of functions of a complex variable will be provided by the 9th edition, just as it was by the earlier editions. The fundamental structure and tone of the earlier editions have been carried over into this new edition. The purpose of this text is to provide a foundation for the theory that underpins the various applications of the topic. You will notice that a particular focus has been placed on the application of conformal mappings as well as residues. Footnotes are provided with references to other texts that contain proofs and discussions of the more delicate results in advanced calculus. This is done so that the course can accommodate the various levels of calculus knowledge possessed by students. The text has been improved by providing more in-depth explanations of the theorems, increasing the amount of detail provided in the arguments, and separating the various topics into their own sections.
