OverviewQuasiregular Mappings extend quasiconformal theory to the noninjective case. They give a natural and beautiful generalization of the geometric aspects of the theory of analytic functions of one complex variable to Euclidean n-space or, more generally, to Riemannian n-manifolds. This book is a self-contained exposition of the subject. A broad spectrum of results of both analytic and geometric metric character are presented, and the methods vary accordingly. The main tools are the variational integral method and the external length method, both of which are thoroughly developed here. Reshetnyak's basic theorem on discreteness and openness is used from the beginning, but the proof by means of variational integrals is postponed until near the end. Thus, the method of external length is being used at an early stage and leads, among other things, to geometric proofs of Picard-type theorems and a defect relation, which are some of the high points of the present book. This book is an introduction to the theory of quasiregular mappings in real n-dimensional space, a new field of mathematical study that has emerged during the past 20 years. The exposition is self-contained and thus accessible to a wide readership. A broad spectrum of results of both analytic and geometric character are presented, and the methods vary accordingly. The main tools are the variational integral method and the external length method, both of which are thoroughly developed here. The author is noted as one of the developers of the theory of quasiregular mappings, particularly for his work in value distribution theory.
