Ricci Solitons Days in Pisa 2011

Expanding Solitons with non-Negative Curvature Operator Coming Out of Cones

speaker: Miles Simon (University of Freiburg)

abstract: We show that a Ricci flow of any complete Riemannian manifold without boundary with bounded non-negative curvature operator and non-zero asymptotic volume ratio exists for all time and has constant asymptotic volume ratio. We show that there is a limit solution, obtained by scaling down this solution at a fixed point in space, which is an expanding soliton coming out of the asymptotic cone at infinity.
