Hamilton's injectivity radius estimate for sequences with almost nonnegative curvature operators
Bennett Chow, Dan Knopf, Peng Lu
Abstract
We give a new and complete proof of Hamilton's injectivity radius estimate for sequences with bounded and almost nonnegative curvature operators, unbounded diameters, and bump-like origins. Such sequences arise in particular from dilations about a singularity of the Ricci flow on a 3-manifold.
