内容简介

The most important topics in the theory, and application of complex variables receive a thorough, coherent treatment in this introductory text. Intended for undergraduates or graduate students in science, mathematics, and engineering, this vohune features hundreds of solved examples, exercises, and applications designed to foster a complete understanding of complex variables as well as an appreciation of" their mathematical beauty and elegance.
Prereqnisites are minimal: a three-semester course in calculus will suffice to prepare students for discussions of these topics: the complex plane, basic properties of analytic time-tions (including a rewritten and reorganized disenssion of Canchy's Theorem), analytic functions as mappings, analytic and harmonic fimetions in applications, and transok)rm methods. Uscful appendices include tables of eonformal mappings and Laplace transfbrms, as well as solutions to odd numbered exercises.
