Opis

Complex Variables: A Physical Approach with Applications, Second Edition offers a notable revision. The emphasis remains on theory and practice. The first part of the text focuses on the fundamental concepts. The author then moves on to a detailed look at how complex variables are used in the real world.

The idea of complex numbers dates back at least 300 years—to Gauss and Euler, among others. Today complex analysis is a central part of modern analytical thinking. It is used in engineering, physics, mathematics, astrophysics, and many other fields. It provides powerful tools for doing mathematical analysis, and often yields pleasing and unanticipated answers.

This book makes the subject of complex analysis accessible to a broad audience. The complex numbers are a somewhat mysterious number system that seems to come out of the blue. It is important for students to see that this is really a very concrete set of objects that has very concrete and meaningful applications.

Features:

• This new edition is a substantial rewrite, focusing on the accessibility, applied, and visual aspect of complex analysis








• This book has an exceptionally large number of examples and a large number of figures.











• The topic is presented as a natural outgrowth of the calculus. It is not a new language, or a new way of thinking.











• Incisive applications appear throughout the book.











• Partial differential equations are used as a unifying theme.
