The recent spectacular work of Perelman [103] removed these obstacles by establishing a local injectivity radius estimate, which is valid for the Ricci flow on compact manifolds in all dimensions. More precisely, Perelman proved two versions of “no local collapsing” property (Theorem 3.3.3 and Theorem 3.3.2), one with an
