Mean curvature flows with cylindrical singularities II: stability and genericity

Ao Sun, Jinxin Xue

In [SX25], we introduced the notion of nondegenerate cylindrical singularity using the ideas from dynamical systems. In this paper, we further study the properties of these singula…

Rigidity and non-rigidity of the stable norm on

Fernando C. Marques, André Neves, Ao Sun

We show that the stable norm of flat metrics on is locally rigid if and locally rigid among metrics of the same volume if . We also sho…

Genus one singularities in mean curvature flow

Adrian Chun-Pong Chu, Ao Sun

We show that for certain one-parameter families of initial conditions in , when we run mean curvature flow, a genus one singularity must appear in one of the flows. Mo…

Generic regularity of Level Set Flows with spherical singularity

Ao Sun, Jinxin Xue

The sphere is well-known as the only generic compact shrinker for mean curvature flow (MCF). In this paper, we characterize the generic dynamics of MCFs with a spherical singularit…

A Generalized Knockoff Procedure for FDR Control in Structural Change Detection

Jingyuan Liu, Ao Sun, Yuan Ke

Controlling false discovery rate (FDR) is crucial for variable selection, multiple testing, among other signal detection problems. In literature, there is certainly no shortage of…
