Sharp dynamical isoperimetric principle for mean curvature flow

Beomjun Choi, Wenkui Du, Seung Chul Park +1

In this paper, we establish a sharp dynamical isoperimetric principle for weak mean curvature flow. We prove that, among weak mean curvature flows with fixed area of initial smooth…

Classification of ancient ovals in higher dimensional mean curvature flow

Beomjun Choi, Wenkui Du, Ziyi Zhao

We study compact non-selfsimilar ancient noncollapsed solutions to the mean curvature flow in $R^{n + 1}$ , called ancient ovals. Our main result is the classification of $k$ …

Rigidity of ancient ovals in higher dimensional mean curvature flow

Beomjun Choi, Wenkui Du, Jingze Zhu

In this paper, we consider the classification of compact ancient noncollapsed mean curvature flows of hypersurfaces in arbitrary dimensions. More precisely, we study $k$ -ovals in $…

Classification of bubble-sheet ovals in $R^{4}$

Beomjun Choi, Panagiota Daskalopoulos, Wenkui Du +2

In this paper, we prove that any bubble-sheet oval for the mean curvature flow in $R^{4}$ , up to scaling and rigid motion, either is the $O (2) \times O (2)$ -…
