Spacelike Mean Curvature Flow [PDF]

open access: yesThe Journal of Geometric Analysis, 2019
AbstractWe prove long-time existence and convergence results for spacelike solutions to mean curvature flow in the pseudo-Euclidean space$$\mathbb {R}^{n,m}$$Rn,m, which are entire or defined on bounded domains and satisfying Neumann or Dirichlet boundary conditions. As an application, we prove long-time existence and convergence of the$${{\,\mathrm{G}\

Non-Parametric Mean Curvature Flow with Prescribed Contact Angle in Riemannian Products

open access: yesAnalysis and Geometry in Metric Spaces, 2022
Assuming that there exists a translating soliton u∞ with speed C in a domain Ω and with prescribed contact angle on ∂Ω, we prove that a graphical solution to the mean curvature flow with the same prescribed contact angle converges to u∞ + Ct as t →∞.

Nonlocal diffusion of smooth sets

open access: yesMathematics in Engineering, 2022
We consider normal velocity of smooth sets evolving by the $ s- $fractional diffusion. We prove that for small time, the normal velocity of such sets is nearly proportional to the mean curvature of the boundary of the initial set for $ s\in [\frac{1}{2},

Curvature-based interface restoration algorithm using phase-field equations.

open access: yesPLoS ONE, 2023
In this study, we propose a restoration algorithm for distorted objects using a curvature-driven flow. First, we capture the convex-hull shaped contour of the distorted object using the mean curvature flow.

Mean curvature flow [PDF]

open access: yesBulletin of the American Mathematical Society, 2015
Mean curvature flow is the negative gradient flow of volume, so any hypersurface flows through hypersurfaces in the direction of steepest descent for volume and eventually becomes extinct in finite time. Before it becomes extinct, topological changes can occur as it goes through singularities. If the hypersurface is in general or generic position, then

Life-Span of Classical Solutions to Hyperbolic Inverse Mean Curvature Flow

open access: yesDiscrete Dynamics in Nature and Society, 2020
In this paper, we investigate the life-span of classical solutions to hyperbolic inverse mean curvature flow. Under the condition that the curve can be expressed in the form of a graph, we derive a hyperbolic Monge–Ampère equation which can be reduced to

Recent rigidity results for graphs with prescribed mean curvature

open access: yesMathematics in Engineering, 2021
This survey describes some recent rigidity results obtained by the authors for the prescribed mean curvature problem on graphs u : M → R. Emphasis is put on minimal, CMC and capillary graphs, as well as on graphical solitons for the mean curvature flow ...

Convergence Rates of the Allen-Cahn Equation to Mean Curvature Flow: A Short Proof Based on Relative Entropies [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2020
We give a short and self-contained proof for rates of convergence of the Allen-Cahn equation towards mean curvature flow, assuming that a classical (smooth) solution to the latter exists and starting from well-prepared initial data. Our approach is based

Forced hyperbolic mean curvature flow [PDF]

open access: yes, 2012
In this paper, we investigate two hyperbolic flows obtained by adding forcing terms in direction of the position vector to the hyperbolic mean curvature flows in \cite{klw,hdl}.
