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.

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.
