半空间或球体中体积约束局部能量最小化集合的唯一性

Uniqueness for volume-constraint local energy-minimizing sets in a half-space or a ball

Chao Xia, Xuwen Zhang

AI总结:

该研究针对满足体积约束的局部能量最小化集合,通过证明庞加莱型不等式,分类了单位球、半空间及楔形域中的此类集合,并证实其相对边界具有光滑性。

摘要:

本文证明了,对任意有限周长集合,若其奇异集的豪斯多夫维数不超过$n-3$,且在保体积扰动下关于自由能量是稳定的,则成立一类庞加莱型不等式。借助该不等式,我们分类了单位球、半空间或楔形区域中所有满足体积约束的局部能量最小化集合。特别地,我们证明了任意能量最小化集合的相对边界是光滑的。

英文摘要:

In this paper, we prove a Poincaré-type inequality for any set of finite perimeter which is stable with respect to the free energy among volume-preserving perturbation, provided that the Hausdorff dimension of its singular set is at most $n-3$. With this inequality, we classify all the volume-constraint local energy-minimizing sets in a unit ball, a half-space or a wedge-shaped domain. In particular, we prove that the relative boundary of any energy-minimizing set is smooth.
