De Giorgi and Gromov working together

N Gigli - arxiv preprint arxiv:2306.14604, 2023 - arxiv.org
The title is meant as way to honor two great mathematicians that, although never actually
worked together, introduced concepts of convergence that perfectly match each other and …

Limits of manifolds with a Kato bound on the Ricci curvature

G Carron, I Mondello, D Tewodrose - arxiv preprint arxiv:2102.05940, 2021 - arxiv.org
We study the structure of Gromov-Hausdorff limits of sequences of Riemannian manifolds
$\{(M_\alpha^ n, g_\alpha)\} _ {\alpha\in A} $ whose Ricci curvature satisfies a uniform Kato …

Ricci curvature bounds and rigidity for non-smooth Riemannian and semi-Riemannian metrics

M Kunzinger, A Ohanyan, A Vardabasso - arxiv preprint arxiv:2406.06762, 2024 - arxiv.org
We study rigidity problems for Riemannian and semi-Riemannian manifolds with metrics of
low regularity. Specifically, we prove a version of the Cheeger-Gromoll splitting theorem\cite …

Ricci Flow under Kato-type curvature lower bound

MC Lee - The Journal of Geometric Analysis, 2024 - Springer
In this work, we extend the existence theory of non-collapsed Ricci flows from point-wise
curvature lower bound to Kato-type curvature lower bound. As an application, we prove that …

Quantitative rigidity of almost maximal volume entropy for both RCD⁎ spaces and integral Ricci curvature bound

L Chen, S Xu - Advances in Mathematics, 2024 - Elsevier
The volume entropy of a compact metric measure space is known to be the exponential
growth rate of the measure lifted to its universal cover at infinity. For a compact Riemannian …

Limits of manifolds with a Kato bound on the Ricci curvature

G Carron, I Mondello, D Tewodrose - Geometry & Topology, 2024 - msp.org
We study the structure of Gromov–Hausdorff limits of sequences of Riemannian manifolds
{(M α n, g α)} α∈ A whose Ricci curvature satisfies a uniform Kato bound. We first obtain …

Almost maximal volume entropy rigidity for integral Ricci curvature in the non-collapsing case

L Chen - The Journal of Geometric Analysis, 2025 - Springer
In this note we will show the almost maximal volume entropy rigidity for manifolds with lower
integral Ricci curvature bound in the non-collapsing case: Given n, d, p> n 2, there exist δ (n …
