Existence of mean curvature flow singularities with bounded mean curvature [PDF]

open access: yesDuke Mathematical Journal, 2020
In [Vel94], Velazquez constructed a countable collection of mean curvature flow solutions in $\mathbb{R}^N$ in every dimension $N \ge 8$. Each of these solutions becomes singular in finite time at which time the second fundamental form blows up.

Mean curvature flow in a Ricci flow background [PDF]

open access: yesCommunications in Mathematical Physics, 2012
Following work of Ecker, we consider a weighted Gibbons-Hawking-York functional on a Riemannian manifold-with-boundary. We compute its variational properties and its time derivative under Perelman's modified Ricci flow.

A remark on soliton equation of mean curvature flow [PDF]

open access: diamondAnais da Academia Brasileira de Ciências, 2004
In this note, we consider self-similar immersions of the mean curvature flow and show that a graph solution of the soliton equation, provided it has bounded derivative, converges smoothly to a function which has some special properties (see Theorem 1.1 ...

Self-Expanders of the Mean Curvature Flow [PDF]

open access: yesVietnam Journal of Mathematics, 2020
We study self-expanding solutions M m ⊂ ℝ n $M^{m}\subset \mathbb {R}^{n}$ of the mean curvature flow. One of our main results is, that complete mean convex self-expanding hypersurfaces are products of self-expanding curves and flat subspaces, if and ...

Mean curvature flow of Reifenberg sets [PDF]

open access: greenGeometry & Topology, 2017
In this paper, we prove short time existence and uniqueness of smooth evolution by mean curvature in $\mathbb{R}^{n+1}$ starting from any $n$-dimensional $(\varepsilon,R)$-Reifenberg flat set with $\varepsilon$ sufficiently small. More precisely, we show that the level set flow in such a situation is non-fattening and smooth.

Fattening in mean curvature flow

open access: yes
For each $g\ge 3$, we prove existence of a compact, connected, smoothly embedded, genus-$g$ surface $M_g$ with the following property: under mean curvature flow, there is exactly one singular point at the first singular time, and the tangent flow at the ...

Numerical analysis for the interaction of mean curvature flow and diffusion on closed surfaces [PDF]

open access: yesNumerische Mathematik, 2022
An evolving surface finite element discretisation is analysed for the evolution of a closed two-dimensional surface governed by a system coupling a generalised forced mean curvature flow and a reaction–diffusion process on the surface, inspired by a ...

Weak-strong uniqueness for volume-preserving mean curvature flow [PDF]

open access: yesRevista matemática iberoamericana, 2022
In this note, we derive a stability and weak-strong uniqueness principle for volume-preserving mean curvature flow. The proof is based on a new notion of volume-preserving gradient flow calibrations, which is a natural extension of the concept in the ...
