WebJul 2, 2024 · We study the collapsing of Calabi-Yau metrics and of Kahler-Ricci flows on fiber spaces where the base is smooth. We identify the collapsed Gromov-Hausdorff limit of the Kahler-Ricci flow when the divisorial part of the discriminant locus has simple normal crossings. In either setting, we also obtain an explicit bound for the real codimension 2 … WebFeb 2, 2024 · The proof heavily uses Cheeger–Colding–Tian theory on Gromov-Hausdorff limits of manifolds with Ricci curvature lower bound, as well as the three-circle theorem. Let us give a sketch. Assume M does not have maximal volume growth, then by taking a tangent cone at infinity, one obtains a limit metric-length space X which is possibly singular. mecca hornsby store

We give the first examples of collapsing Ricci limit spaces on which the Hausdorff dimension of the singular set exceeds that of the regular set; moreover, the Hausdorff dimension of these spaces can be non-integers. This answers a question of Cheeger-Colding [ CC00a, Page 15] about collapsing Ricci limit spaces.

WebMy main research interests lie in geometric analysis, and more specifically, intrinsic and extrinsic geometric flows, with an emphasis on Ricci flow and its applications to geometry and topology. I am also interested in some other geometric PDEs, such as Cheeger-Colding theory and its applications to Riemannian and Kaehler geometry. WebWe aim to further exploit this ansatz by allowing edge singularities in the construction, from which one can see some new and intriguing geometric features relating to canonical edge metrics, Sasakian geometry, Cheeger--Colding theory, K-stability and normalized volume.
