The purpose of this volume and of the other volumes in the same series is to provide a collection of surveys that allows the reader to learn the important aspects of William Thurston’s heritage. Thurston’s ideas have altered the course of twentieth century mathematics, and they continue to have a significant influence on succeeding generations of mathematicians. The topics covered in the present volume include com-plex hyperbolic Kleinian groups, Möbius structures, hyperbolic ends, cone 3-manifolds, Thurston’s norm, surgeries in representation varieties, triangulations, spaces of polygo-nal decompositions and of singular flat structures on surfaces, combination theorems in the theories of Kleinian groups, hyperbolic groups and holomorphic dynamics, the dynamics and iteration of rational maps, automatic groups, and the combinatorics of right-angled Artin groups.

This book consists of 16 surveys on Thurston's work and its later development. The authors are mathematicians who were strongly influenced by Thurston's publications and ideas. The subjects discussed include, among others, knot theory, the topology of 3-manifolds, circle packings, complex projective structures, hyperbolic geometry, Kleinian groups, foliations, mapping class groups, Teichmüller theory, anti-de Sitter geometry, and co-Minkowski geometry. The book is addressed to researchers and students who want to learn about Thurston’s wide-ranging mathematical ideas and their impact. At the same time, it is a tribute to Thurston, one of the greatest geometers of all time, whose work extended over many fields in mathematics and who had a unique way of perceiving forms and patterns, and of communicating and writing mathematics.

The author invites the reader to share her contemplative immersion in the world of Celtic culture and spirituality. Thurston's poetry exposes us to the unyielding harshness of early medieval life in what is now Scotland, Ireland, and Wales, and to the robust and original spirituality.

Another title in the best-selling '25' series, using the same popular format. Over the last fifteen or so years, the 2/1 Game Forcing bidding method has gained substantial popularity, but for various reasons it is not taught in beginner classes. This book is therefore designed for players who are familiar with Standard bidding and are interested in switching to the 2/1 method. It covers basic concepts as well as the differences between 2/1 and Standard auctions, and includes a discussion of more advanced ideas and conventions that fit particularly well with 2/1 methods. Existing books on this topic (notably by Max Hardy and Mike Lawrence) are too advanced and/or too technical for this level of player.
