Sasakian Geometry and Einstein Metrics on Spheres
Charles P. Boyer, Krzysztof Galicki
Abstract
This paper is based on a talk presented by the first author at the Short Program on Riemannian Geometry that took place at the Centre de Recherche Mathématiques, Université de Montréal, during the period June 28-July 16, 2004. It is a report on our joint work with János Kollár concerning the existence of an abundance of Einstein metrics on odd dimensional spheres, including exotic spheres.
