AN INTRODUCTION TO THE THEORY OF MULTIPLY PERIODIC FUNCTIONS BY H. F. BAKER, Sc. D., F. R.

PREFACE. present volume consists of two parts the first of these deals with the theory of hyperelliptic functions of two variables, the second with the reduction of the theory of general multiply-periodic functions to the theory of algebraic functions taken together they furnish what is intended to be an elementary and self-contained introduction to many of the leading ideas of the theory of multiply-periodic functions, with the incidental aim of aiding the comprehensionof the importance of this theory in analytical geometry. The first part is centred round some remarkable differential equations satisfied by the functions, which appear to be equally illuminative both of the analytical and geometrical aspects of the theory it was in fact to explain this that the book was originally entered upon. The account has no pretensions to completeness being anxious to explain the properties of the functions from the beginning, I have been debarred from following Humberts brilliant monograph, which assumes from the first Poincares theorem as to the number of zeros common to two theta functions this theorem is reached in this volume, certainly in a generalised form, only in the last chapter of Part n. being anxious to render the geometrical portions of the volume quite elementary, I have not been able to utilise the theory of quadratic complexes, which vi Preface. has proved so powerful in this connexion in the hands of Kummer and Klein and, for both these reasons, the account given here, and that given in the remarkable book from the pen of R. W. H. T. Hudson, will, I believe, only be regarded by readers as comple mentary. The theory of Kummers surface, and of the theta functions, has been much studied since the year 1847 or before in which Gopel first obtained the biquadratic relation connecting four theta functions and Wirtinger has shewn, in his Unter suchungen iiber Thetafunctionen, which has helped me in several ways in the second part of this volume, that the theory is capable of generalisation, in many of its results, to space of 2 1 dimensions but even in the case of two variables there is a certain inducement, not to come to too close quarters with thedetails, in the fact of the existence of sixteen theta functions connected together by many relations, at least in the minds of beginners. I hope therefore that the treatment here followed, which reduces the theory, in a very practical way, to that of one theta function and three periodic functions connected by an algebraic equation, may recommend itself to others, and, in a humble way, serve the purpose of the earlier books on elliptic functions, of encouraging a wider use of the functions in other branches of mathematics...

James Joseph Sylvester (1814-97) was an English mathematician who made key contributions to numerous areas of his field and was also of primary importance in the development of American mathematics, both as inaugural Professor of Mathematics at Johns Hopkins University and founder of the American Journal of Mathematics. Originally published in 1912, this book forms the fourth in four volumes of Sylvester's mathematical papers, covering the period from 1882 to 1897. Together these volumes provide a comprehensive resource that will be of value to anyone with an interest in Sylvester's theories and the history of mathematics.

Henry Frederick Baker (1866 1956) was a renowned British mathematician specialising in algebraic geometry. He was elected a Fellow of the Royal Society in 1898 and appointed the Lowndean Professor of Astronomy and Geometry in the University of Cambridge in 1914. First published between 1922 and 1925, the six-volume Principles of Geometry was a synthesis of Baker's lecture series on geometry and was the first British work on geometry to use axiomatic methods without the use of co-ordinates. The first four volumes describe the projective geometry of space of between two and five dimensions, with the last two volumes reflecting Baker's later research interests in the birational theory of surfaces. The work as a whole provides a detailed insight into the geometry which was developing at the time of publication. This, the second volume, describes the principal configurations of space of two dimensions.
