本文研究了具有Dirichlet条件的平均曲率水平集流的粘性平衡问题。主要结果表明,平衡解的几乎每个水平集都是从Hausdorff维数最多为n-8的奇异集解析的,并且这些水平集相对于面积泛函是平稳且稳定的。开发的一个关键工具是一个最大值原则的障碍问题的解决方案,其中的障碍(粘度)最小的表面。对于相应的初边值问题,当t → ∞时,也证明了其收敛于平衡点.
In this paper we consider viscosity equilibria to the mean curvature level set flow with a Dirichlet condition. The main result shows that almost every level set of an equilibrium solution is analytic off of a singular set of Hausdorff dimension at most n − 8 and that these level sets are stationary and stable with respect to the area functional. A key tool developed is a maximum principle for solutions to obstacle problems where the obstacle consists of (viscosity) minimal surfaces. Convergence to equilibrium as t → ∞ is also established for the associated initial-boundary value problem.
