Web(7) Cheeger–Gromov Ł topology, 26.5.2024 The Cheeger–Gromov Ł topology is much stronger than the Lipschitz topology but gives more useful geometric information. The Fundamental Lemma of Riemannian Convergence Theory gives a compactness criterion for families of Riemannian manifolds with “uniformly controlled atlases”. WebAs their applications, we obtain some optimal Cheeger–Gromov–Taylor type compact theorems, volume growth and Mckean type estimate for the first Dirichlet eigenvalue for such manifolds. Although we present the results for Finsler manifolds, they are all new results for Riemannian manifolds.

WebBefore discussing collapsing in detail, we recall the Cheeger-Gromov compactness theorem [11, 12, 36], which, in its pointed version, controls the thick part. A sequence of Riemannian n-manifolds, (Mi,gi), is said to converge in the C1,α-topology to a C1,α manifold (M ∞,g∞)if there are diffeomorphisms fi: M∞ →Mi such that the ... WebApr 1, 2024 · A Cheeger–Gromov–Taylor-type theorem. In this section, we prove Theorem 13. Our proof of this theorem is a modification of the proofs of Cheeger–Gromov–Taylor-type theorems by Y. Soylu [29] and the author [33]. In order to prove this theorem, we again use the index form of a unit speed-minimizing geodesic segment. Proof of Theorem 13 WebOrientado (s) Michael O’Nan.
