Preface
In writing this book, I have tried to keep in mind the student of rather modest mathematical preparation, presupposing only a first course in function theory. Thus, I have included such things as a proof of Schwarz's inequality, theorems on uniformly bounded families of analytic functions, properties of Stieltjes integrals, and an introduction to the matrix calculus. I have presupposed a knowledge of the elementary properties of linear fractional transformations in the complex plane.

It has not been my intention to write a complete treatise on the subject of continued fractions, covering all the literature, but rather to present a unified theory correlating certain parts and applications of the subject within a larger analytic structure. I have not touched upon the arithmetic theory, and have, for the most part, refrained from developing formulas of a more general character than are actually used in the proofs. Neither have I made any attempt to compile a complete bibliography.

Certain parts of the book have been developed in courses. For instance, parts of Chapter X were used in a course in the theory of equations, and most of Part I was covered in a course in the theory of continued fractions. Some of the material of Chapters XII and XV was developed in seminar courses.

This approach to the theory of continued fractions is mainly the result of researches carried on during the past decade by my students and colleagues and myself. ...
