有障碍物的中曲率流:粘性方法

Mean curvature flow with obstacles: a viscosity approach

Gwenael Mercier

摘要:

我们引入了一个水平集公式的中曲率流与障碍,并证明了黏性解的存在性和唯一性。这些结果推广了Evans和Spruck及Chen,Giga和Goto于1991年提出的无障碍中曲率流的粘性方法。此外,我们还证明了这种演化与Almeida,Chambolle和Novaga(2012)引入的变分方案是一致的,并且我们研究了我们的黏性解的长时间行为。

英文摘要:

We introduce a level-set formulation for the mean curvature flow with obstacles and show existence and uniqueness of a viscosity solution. These results generalize a well known viscosity approach for the mean curvature flow without obstacle by Evans and Spruck and Chen, Giga and Goto in 1991. In addition, we show that this evolution is consistent with the variational scheme introduced by Almeida, Chambolle and Novaga (2012) and we study the long time behavior of our viscosity solutions.
