Unique asymptotics of $S O (k) \times S O (n - k + 1)$ symmetric ancient ovals of Ricci flow

Panagiota Daskalopoulos, Wenkui Du, Natasa Sesum +1

We obtain the unique asymptotics of $S O (k) \times S O (n - k + 1)$ -invariant, compact, simply-connected, {factorwisely non-self-similar} $n$ -dimensional $κ$ -solutions of the Ricci flow $(…

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 $O (2) \times O (2)$ -…
