Solution of a Ricci pinching conjecture in three dimensions

speaker: John Lott (University of California)

abstract: The conjecture said that a complete Riemannian 3-manifold with pointwise pinched nonnegative Ricci curvature is compact or flat. It has been proved through the efforts of myself, Deruelle-Schulze-Simon and Lee-Topping. I'll describe the background to the conjecture and the main ideas of the proof, which uses Ricci flow.
