backward propagation of warped-product structures under the ricci flow and asymptotically conical shrinkers

abstract:

we establish sufficient conditions for a locally-warped product structure to propagate backward in time under the ricci flow. as an application, we show that if a gradient shrinking soliton is asymptotic to a cone whose cross-section is a locally warped product of einstein manifolds, the soliton must itself be a warped product over the same manifolds.
