具有体积约束的中曲率流的平流解

Flat flow solution to the mean curvature flow with volume constraint

Vesa Julin

摘要:

在本文中,我将通过Mugnai-Seis-Spadaro(2016)的离散最小化运动方案重新构建体积保持中曲率流的全局弱解。这种方法是基于Almante-Taylor-Wang(1993)和Luckhaus-Strurzenhecker(1995)的梯度流方法,我的目的是通过在离散格式中直接实现体积约束来代替体积惩罚,从实际的观点来看,这可能更自然。技术新颖性是基于能量的二阶变分条件的密度估计的证明。

英文摘要:

In this paper I will revisit the construction of a global weak solution to the volume preserving mean curvature flow via discrete minimizing movement scheme by Mugnai-Seis-Spadaro (2016). This method is based on the gradient flow approach due to Almgren-Taylor-Wang (1993) and Luckhaus-Strurzenhecker (1995) and my aim is to replace the volume penalization by implementing the volume constraint directly in the discrete scheme, which from practical point of view is perhaps more natural. A technical novelty is the proof of the density estimate which is based on the second variation condition of the energy.
