Cheeger colding naber theory

WebCheeger-Colding- Naber Theory: Abstract: Cheeger-Colding- Naber Theory (CCN) provides us with tools to study limit spaces of Riemannian Manifolds, and tries to answer the question: how degenerate can the limit space be? In this talk, rather than studying CCN Theory itself, we will present the tools needed to understand the results that follow ... WebMar 11, 2024 · In this talk we will survey some of the developments of Cheeger and Colding’s conjecture on a sequence of n dimensional manifolds with uniform two sides Ricci Curvature bound, investigated by Anderson, Tian, Cheeger, Colding and Naber among others. The conjecture states that every Gromov-Hausdorff limit of the above-mentioned …
