William Thurston (1946-2012) was one of the great mathematicians of the twentieth century. He was a visionary whose extraordinary
ideas revolutionized a broad range of areas of mathematics, from foliations, contact structures, and Teichmuller theory to
automorphisms of surfaces, hyperbolic geometry, geometrization of 3-manifolds, geometric group theory, and rational maps.
In addition, he discovered connections between disciplines that led to astonishing breakthroughs in mathematical understanding
as well as the creation of entirely new fields. His far-reaching questions and conjectures led to enormous progress by other
researchers. In What's Next?, many of today's leading mathematicians describe recent advances and future directions inspired
by Thurston's transformative ideas.This book brings together papers delivered by his colleagues and former students at "e;What's
Next? The Mathematical Legacy of Bill Thurston,"e; a conference held in June 2014 at Cornell University. It discusses
Thurston's fundamental contributions to topology, geometry, and dynamical systems and includes many deep and original contributions
to the field. Incisive and wide-ranging, the book explores how he introduced new ways of thinking about and doing mathematics-innovations
that have had a profound and lasting impact on the mathematical community as a whole-and also features two papers based on
Thurston's unfinished work in dynamics.
