非局部极小曲面

Nonlocal minimal surfaces

L. A. Caffarelli, J. -M. Roquejoffre, O. Savin

摘要:

极小曲面的de Giorgi理论包括研究其指示函数是BV范数的(局部)最小值的集合。在本文中,我们用$H^σ$范数代替BV范数,用$σ<1/2$,并试图理解极小化器是什么样子的。平行于de Giorgi理论,我们证明,如果一个极小的边界是足够平坦的单位球,那么它是一个光滑的一块超曲面。

英文摘要:

The de Giorgi theory for minimal surfaces consists in studying sets whose indicator function is a (local) minimum of the BV norm. In this paper we replace the BV norm by the $H^σ$ norm, with $σ<1/2$, and try to understand what the minimisers look like. Parallel to the de Giorgi theory we prove that, if the boundary of a minimiser is sufficiently flat in the unit ball, then it is a smooth piece of hypersurface.
