Mullins-Sekerka问题中平面界面的最优松弛

Optimal relaxation to a planar interface in the Mullins-Sekerka problem

Olga Chugreeva, Felix Otto, Maria G. Westdickenberg

摘要:

我们分析的收敛速度的Mullins-Sekerka模型中的平面界面应用松弛法之间的距离,能量和耗散的关系的基础上。松弛法是由两位作者在1-D Cahn-Hilliard方程的背景下开发的,目前的工作是一个扩展到一个更高维的问题,其中界面的曲率起着重要的作用。在给定初始数据的假设条件下,得到的收敛速度是最优的。

英文摘要:

We analyze the convergence rates to a planar interface in the Mullins-Sekerka model by applying a relaxation method based on relationships among distance, energy, and dissipation. The relaxation method was developed by two of the authors in the context of the 1-d Cahn-Hilliard equation and the current work represents an extension to a higher dimensional problem in which the curvature of the interface plays an important role. The convergence rates obtained are optimal given the assumptions on the initial data.
