Complex Analysis

This is the fourth edition of Serge Lang's Complex Analysis. The first part of the book covers the basic material of complex analysis, and the second covers many special topics, such as the Riemann Mapping Theorem, the gamma function, and analytic continuation. Power series methods are used more systematically than in other texts, and the proofs using these methods often shed more light on the results than the standard proofs do.

Written by a well-known and somewhat controversial Springer author whose writing style has achieved a considerable following Unique approach should appeal to those who want to obtain new results in this field Goes beyond the basic material to present special topics of current interest Additional topics covered in the second part give readers a great deal of flexibility in structuring their learning of the subject Extensively revised edition, includes new examples and exercises, and hundreds of minor improvements throughout
