A gradient flow of isometric structures
Shubham Dwivedi, Panagiotis Gianniotis, Spiro Karigiannis
We study a flow of structures which induce the same Riemannian metric which is the negative gradient flow of an energy functional. We prove Shi-type estimates for the torsion…

Diameter and curvature control under mean curvature flow
Panagiotis Gianniotis, Robert Haslhofer
We prove that for the mean curvature flow of two-convex hypersurfaces the intrinsic diameter stays uniformly controlled as one approaches the first singular time. We also derive sh…
