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. Let T_{x^*}X be a tangent cone at x^*\in X. Then there is a length space Ysuch that The proof depends on the following lemmas. We start with some estimates of approximate harmonic functions.

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 …
