An Introduction to Complex Analysis

This textbook introduces the subject of complex analysis to advanced undergraduate and graduate students in a clear and concise manner.

Key features of this textbook:

-Effectively organizes the subject into easily manageable sections in the form of 50 class-tested lectures

• Uses detailed examples to drive the presentation

-Includes numerous exercise sets that encourage pursuing extensions of the material, each with an "Answers or Hints" section

-covers an array of advanced topics which allow for flexibility in developing the subject beyond the basics

-Provides a concise history of complex numbers

An Introduction to Complex Analysis will be valuable to students in mathematics, engineering and other applied sciences. Prerequisites include a course in calculus.
