Complex Analysis

This book organizes the basic material of complex analysis in a unique manner.The first part of the book is a study of the many equivalent ways of understanding the concept of analyticity. The many ways of formulating the concept of an analytic function are summarized in what we term the Fundamental Theorem for functions of a complex variable. The organization of these conditions into a single unifying theorem is a hallmark of Bers's mathematical style with an emphasis on clarity and elegance. Here it provides a conceptual framework for results that are highly technical and often computational. The framework comes from an insight that, once articulated, will drive the subsequent mathematics and lead to new results.In the second part, the text proceeds to a leisurely exploration of interesting ramifications of the main concepts.The book covers most, if not all, of the material contained in Bers s courses on first year complex analysis. In addition, topics of current interest such as zeros of holomorphic functions and the connection between hyperbolic geometry and complex analysis are explored.The organization of material in this book allows for an elegant and economical treatment of many important topics.
