The mean curvature flow in Minkowski spaces [PDF]

open access: yesScience China Mathematics, 2018
Studying the geometric flow plays a powerful role in mathematics and physics. In this paper, we introduce the mean curvature flow on Finsler manifolds and give a number of examples of the mean curvature flow. For Minkowski spaces, a special case of Finsler manifolds, we will prove the existence and uniqueness for solution of the mean curvature flow and

The fractional mean curvature flow

open access: yesBruno Pini Mathematical Analysis Seminar, 2020
In this note, we present some recent results in the study of the fractional mean curvature flow, that is a geometric evolution of the boundary of a set whose speed is given by the fractional mean curvature.

Pinched hypersurfaces are compact

open access: yesAdvanced Nonlinear Studies, 2023
We make rigorous and old idea of using mean curvature flow to prove a theorem of Richard Hamilton on the compactness of proper hypersurfaces with pinched, bounded curvature.

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 →∞.

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 of Voronoi Diagrams [PDF]

open access: yesJournal of Nonlinear Science, 2014
We study the evolution of grain boundary networks by the mean-curvature flow under the restriction that the networks are Voronoi diagrams for a set of points. For such evolution we prove a rigorous universal upper bound on the coarsening rate. The rate agrees with the rate predicted for the evolution by mean-curvature flow of the general grain boundary

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

Multi-Reconstruction from Points Cloud by Using a Modified Vector-Valued Allen–Cahn Equation

open access: yesMathematics, 2021
The Poisson surface reconstruction algorithm has become a very popular tool of reconstruction from point clouds. If we reconstruct each region separately in the process of multi-reconstruction, then the reconstructed objects may overlap with each other ...
