The Ubiquitous Quasidisk
Share this pageFrederick W. Gehring; Kari Hag
This book focuses on gathering the numerous properties and many
different connections with various topics in geometric function theory
that quasidisks possess. A quasidisk is the image of a disk under a
quasiconformal mapping of the Riemann sphere. In 1981 Frederick
W. Gehring gave a short course of six lectures on this topic in
Montreal and his lecture notes “Characteristic Properties of
Quasidisks” were published by the University Press of the University
of Montreal. The notes became quite popular and within the next decade
the number of characterizing properties of quasidisks and their
ramifications increased tremendously. In the late 1990s Gehring and
Hag decided to write an expanded version of the Montreal notes. At
three times the size of the original notes, it turned into much more
than just an extended version. New topics include two-sided
criteria. The text will be a valuable resource for current and future
researchers in various branches of analysis and geometry, and with its
clear and elegant exposition the book can also serve as a text for a
graduate course on selected topics in function theory.
Frederick W. Gehring (1925–2012) was a leading figure in the
theory of quasiconformal mappings for over fifty years. He received
numerous awards and shared his passion for mathematics generously by
mentoring twenty-nine Ph.D. students and more than forty postdoctoral
fellows.
Kari Hag received her Ph.D. under Gehring's direction in 1972 and
worked with him on the present text for more than a decade.

Reviews & Endorsements
...This text on quasidisks provides a cross section of the plane quasiconformal theory and demonstrates the many ways in which these mappings are related to analysis, topology, geometry and other parts of mathematics. The exposition is very clear and the text is richly illustrated with carefully drawn pictures. This book would be an excellent choice for a first book on plane quasiconformal maps for a graduate student. It is also a valuable source of inspiration for researchers of complex analysis, because the material covers many topics of current interest. It is my guess that this book will be an instant classic in its field.
