Local Ricci flow and limits of non-collapsed regions whose Ricci curvature is bounded from below
11:10 Fri 26 Oct, 2018 :: Barr Smith South Polygon Lecture theatre :: Miles Simon :: University of Magdeburg

We use a local Ricci flow to obtain a bi-Holder correspondence between non-collapsed (possibly non-complete) 3-manifolds with Ricci curvature bounded from below and Gromov-Hausdorff limits of sequences thereof. This is joint work with Peter Topping and the proofs build on results and ideas from recent papers of Hochard and Topping+Simon.
