Ricci Flow and the Sphere Theorem
Share this pageSimon Brendle
In 1982, R. Hamilton introduced a nonlinear evolution equation for
Riemannian metrics with the aim of finding canonical metrics on manifolds.
This evolution equation is known as the Ricci flow, and it has since been
used widely and with great success, most notably in Perelman's solution of
the Poincaré conjecture. Furthermore, various convergence theorems have
been established.
This book provides a concise introduction to the subject as well as a
comprehensive account of the convergence theory for the Ricci flow. The
proofs rely mostly on maximum principle arguments. Special emphasis is
placed on preserved curvature conditions, such as positive isotropic
curvature. One of the major consequences of this theory is the
Differentiable Sphere Theorem: a compact Riemannian manifold, whose
sectional curvatures all lie in the interval (1,4], is diffeomorphic to a
spherical space form. This question has a long history, dating back to a
seminal paper by H. E. Rauch in 1951, and it was resolved in 2007 by the
author and Richard Schoen.
This text originated from graduate courses given at ETH Zürich
and Stanford University, and it is directed at graduate students and
researchers. The reader is assumed to be familiar with basic
Riemannian geometry, but no previous knowledge of Ricci flow is
required.
Readership
Graduate students and research mathematicians interested in differential geometry and topology of manifolds.
Reviews & Endorsements
This book is a great self-contained presentation of one of the most important and exciting developments in differential geometry. It is highly recommended for both researchers and students interested in differential geometry, topology and Ricci flow. As the main technical tool used in the book is the maximum principle, familiar to any undergraduate, this book would make a fine reading course for advanced undergraduates or postgraduates and, in particular, is an excellent introduction to some of the analysis required to study Ricci flow.
-- Huy The Nyugen, Bulletin of the LMS
This is an excellent self-contained account of exciting new developments in mathematics suitable for both researchers and students interested in differential geometry and topology and in some of the analytic techniques used in Ricci flow. I very strongly recommend it.
