我们继续我们的分析阈值计划从变分的观点,并证明了一个条件收敛的结果对Brakke的平均曲率流的概念。我们的证明是基于一个本地化的版本的最小化运动的解释,Esedoetlu和第二作者。我们应用De Giorgi的变分插值的阈值计划,并通过在所产生的能量耗散不等式的限制。结果是有条件的,在这个意义上,我们假设的时间积分的能量的近似收敛到那些的限制。
We continue our analysis of the thresholding scheme from the variational viewpoint and prove a conditional convergence result towards Brakke’s notion of mean curvature flow. Our proof is based on a localized version of the minimizing movements interpretation of Esedoğlu and the second author. We apply De Giorgi’s variational interpolation to the thresholding scheme and pass to the limit in the resulting energy-dissipation inequality. The result is conditional in the sense that we assume the time-integrated energies of the approximations to converge to those of the limit.
