Pseudo-locality for a coupled Ricci flow

Differential Geometry 2015-11-30 v3

Abstract

Let (M,g,ϕ)(M,g,\phi) be a solution to the Ricci flow coupled with the heat equation for a scalar field ϕ\phi. We show that a complete, κ\kappa-noncollapsed solution (M,g,ϕ)(M,g,\phi) to this coupled Ricci flow with a Type I singularity at time T<T<\infty will converge to a non-trivial Ricci soliton after parabolic rescaling, if the base point is Type I singular. A key ingredient is a version of Perelman pseudo-locality for the coupled Ricci flow.
