Ricci flows which terminate in cones

Brett Kotschwar

We prove that a complete solution to the Ricci flow on $M \times [- T, 0)$ which has quadratic curvature decay on some end of $M$ and converges locally smoothly to the end of a cone…

Backward propagation of warped product structures and asymptotically conical shrinkers

Brett Kotschwar

We establish sufficient conditions which ensure that a locally-warped product structure propagates backward in time under the Ricci flow. As an application, we prove that if an asy…
