# An Introduction to the Theory of Higher-Dimensional Quasiconformal Mappings

Share this page
*Frederick W. Gehring; Gaven J. Martin; Bruce P. Palka*

This book offers a modern, up-to-date
introduction to quasiconformal mappings from an explicitly geometric
perspective, emphasizing both the extensive developments in mapping
theory during the past few decades and the remarkable applications of
geometric function theory to other fields, including dynamical
systems, Kleinian groups, geometric topology, differential geometry,
and geometric group theory. It is a careful and detailed introduction
to the higher-dimensional theory of quasiconformal mappings from the
geometric viewpoint, based primarily on the technique of the conformal
modulus of a curve family. Notably, the final chapter describes the
application of quasiconformal mapping theory to Mostow's celebrated
rigidity theorem in its original context with all the necessary
background.

This book will be suitable as a textbook for
graduate students and researchers interested in beginning to work on
mapping theory problems or learning the basics of the geometric
approach to quasiconformal mappings. Only a basic background in
multidimensional real analysis is assumed.

#### Readership

Graduate students and researchers interested in mapping theory.

#### Reviews & Endorsements

GMP are to be commended for writing their monograph with a remarkable attention to detail...Readers keen to engage with the material could easily attempt to prove any of the results as exercises. I am confident that this book will very soon become a standard basic reference.

-- Tushar Das, MAA Reviews

The content of this book is precisely articulated while an inviting and, at times, conversational tone is maintained. This combination makes for a pleasant reading experience. The presentation of content is clearly organized and follows a natural progression of ideas.

-- David Matthew Freeman, Mathematical Reviews

[T]he book takes a wider approach to the modern theory of quasiconformal mappings and its applications than what is usual in more specialized books.
