Cauchy and the Creation of Complex Function Theory

Description

In this book, Dr. Smithies analyzes the process through which Cauchy created the basic structure of complex analysis, describing first the eighteenth century background before proceeding to examine the stages of Cauchy's own work, culminating in the proof of the residue theorem and his work on expansions in power series. Smithies describes how Cauchy overcame difficulties including false starts and contradictions brought about by over-ambitious assumptions, as well as the improvements that came about as the subject developed in Cauchy's hands. Controversies associated with the birth of complex function theory are described in detail. Throughout, new light is thrown on Cauchy's thinking during this watershed period. This book is the first to make use of the whole spectrum of available original sources and will be recognized as the authoritative work on the creation of complex function theory.

From the hardback review: 'This exemplary book is the first thorough and comprehensive presentation of Cauchy's creation between 1814 and 1831, of complex function theory ... the papers form a diary that testifies to the gradual development of a new field in the mind of an outstanding mathematician.' D. Laugwitz, Darmstadt From the hardback review: ' ... an invaluable guide to anyone interested in the work of a great mathematician'. Jeremy Gray, The Open University From the hardback review: 'This book is a welcome contribution to the history of mathematical ideas. It is carefully written ... in the case of a great mathematician of the first half of the nineteenth century, it is very useful to have a book analyzing his ideas. Smithie's book helps us understand the technical achievements of Cauchy in founding the theory of complex functions.' The Mathematical Gazette From the hardback review: '... new light is thrown on Cauchy's thinking.' L'Enseignment Mathematique From the hardback review: '... a unique source not only for the historians of mathematics but to all who are fascinated by the beauty of the complex function theory.'
