Ru Min. Nevanlinna Theory and Its Relation to Diophantine Approximation

World Scientific, 2001. — 330 p. — ISBN 981-0244029.Diophantine equations are systems of polynomial equations to be solved in integers, in rational numbers, or in various generalizations, such as finitely generated rings over Z or finitely generated fields over Q. Diophantine approximation is the study of Diophantine equations using the method of approximations. The Nevanlinna theory, on the other hand, studies holomorphic solutions of the systems of polynomial equations. More precisely, since the complex solutions to a system of polynomial equations form an algebraic variety, Diophantine approximation studies the rational points in algebraic varieties defined over Q and Nevanlinna theory investigates the properties of holomorphic curves in algebraic varieties. Nevanlinna theory and Diophantine approximation have developed independently of one another for several decades. It has been, however, discovered by C.F. Osgood, P. Vojta, Serge Lang and others that a number of striking similarities exist between these two subjects. Generally speaking, a non-constant holomorphic curve in an algebraic variety corresponds to an infinite set of rational points, so, in this way, any theorem in Nevanlinna theory should translate into a true statement in Diophantine approximation. A growing understanding of these connections over the last 15 years has led to significant advances in both fields. Outstanding conjectures from decades ago are being solved.
This book presents, in a systematic and almost self-contained way, the analogy between the Nevanlinna theory and Diophantine approximation. Although the emphasis is on Nevanlinna theory, both theories are presented in this book, including some results of recent research. We divide each chapter into Part A and Part B. Part A deals with Nevanlinna theory and Part B covers Diophantine approximation. At the end of each chapter, a table is provided to indicate the correspondence of the theorems.Файл: отскан. стр.
