平均凸集的中曲率流的阈值格式的Strong convergence

Strong convergence of the thresholding scheme for the mean curvature flow of mean convex sets

Jakob Fuchs, Tim Laux

摘要:

在这项工作中,我们分析了Merriman,Bence和Osher的阈值计划,时间离散的中曲率流。我们限制到两个阶段的设置和平均凸的初始条件。在这个意义上的最小化运动的解释Esedoglu和奥托,我们显示的时间积分能量的近似收敛到时间积分能量的限制。作为推论,Otto和作者之一的条件收敛结果在两相平均凸情形下成为无条件的。我们的结果是一般性的,足以处理扩展的计划,各向异性流的非负内核可以选择。

英文摘要:

In this work, we analyze Merriman, Bence and Osher's thresholding scheme, a time discretization for mean curvature flow. We restrict to the two-phase setting and mean convex initial conditions. In the sense of the minimizing movements interpretation of Esedoglu and Otto we show the time-integrated energy of the approximation to converge to the time-integrated energy of the limit. As a corollary, the conditional convergence results of Otto and one of the authors become unconditional in the two-phase mean convex case. Our results are general enough to handle the extension of the scheme to anisotropic flows for which a non-negative kernel can be chosen.
