# Function Theory in Several Complex Variables

Share this page
*Toshio Nishino*

“Kiyoshi Oka, at the beginning of his research, regarded the collection of problems which he encountered in the study of domains of holomorphy as large mountains which separate today and tomorrow. Thus, he believed that there could be no essential progress in analysis without climbing over these mountains … this book is a worthwhile initial step for the reader in order to understand the mathematical world which was created by Kiyoshi Oka.”

This book explains results in the theory of functions of several complex variables which were mostly established from the late nineteenth century through the middle of the twentieth century. In the work, the author introduces the mathematical world created by his advisor, Kiyoshi Oka.

In this volume, Oka's work is divided into two parts. The first is the study of analytic functions in univalent domains in \({\mathbf C}^n\). Here Oka proved that three concepts are equivalent: domains of holomorphy, holomorphically convex domains, and pseudoconvex domains; and moreover that the Poincaré problem, the Cousin problems, and the Runge problem, when stated properly, can be solved in domains of holomorphy satisfying the appropriate conditions. The second part of Oka's work established a method for the study of analytic functions defined in a ramified domain over \({\mathbf C}^n\) in which the branch points are considered as interior points of the domain. Here analytic functions in an analytic space are treated, which is a slight generalization of a ramified domain over \({\mathbf C}^n\).

In writing the book, the author's goal was to bring to readers a real understanding of Oka's original papers. This volume is an English translation of the original Japanese edition, published by the University of Tokyo Press (Japan). It would make a suitable course text for advanced graduate level introductions to several complex variables.

#### Readership

Graduate students and research mathematicians interested in several complex variables.

#### Reviews & Endorsements

This book has its own point of view, and it is one that is not well represented in the more modern books. So it is a welcome addition to the literature … I conclude by noting that the translation is a particularly mellifluous one. The book is a pleasure to read.
