最小化分区的中曲率流的移动

Minimizing movements for mean curvature flow of partitions

Giovanni Bellettini, Shokhrukh Yusufovich Kholmatov

摘要:

利用极小化运动的方法证明了空间中有界划分的弱整体时间中曲率流的存在性。结果被扩展到适当的驱动力存在的情况下。我们还证明了当进化从正距离有界集合的并进行的划分开始时,最小化运动解与光滑解和黏性解的一些一致性结果。此外,从正距离凸集并出发的运动与经典的中曲率流一致,并且关于初始划分的Hausdorff收敛是稳定的.

英文摘要:

We prove the existence of a weak global in time mean curvature flow of a bounded partition of space using the method of minimizing movements. The result is extended to the case when suitable driving forces are present. We also prove some consistency results for a minimizing movement solution with smooth and viscosity solutions when the evolution starts from a partition made by a union of bounded sets at a positive distance. In addition, the motion starting from the union of convex sets at a positive distance agrees with the classical mean curvature flow and is stable with respect to the Hausdorff convergence of the initial partitions.
