Backwards uniqueness of the Ricci flow

Brett Kotschwar

Published 2009-06-26Version 1

In this paper, we prove a unique continuation or ``backwards-uniqueness'' theorem for solutions to the Ricci flow. A particular consequence is that the isometry group of a solution cannot expand within the lifetime of the solution.
