Complex Functions of a Variable

This book is intended as a first course in the theory of functions of a single complex variable for students (of Engineering, Physics or Mathematics) who have already acquired the fundamental notions of real Mathematical Analysis. It is the English version of an older book, published by Springer in Italian, based on the lectures given by the author to the students of the University of Rome "La Sapienza" and of the Scuola Superiore di Catania.
