AI总结:

本文证明了一类varifolds的Michael-Simon不等式,在余维数2时达到尖锐,并由此得到等号仅在圆盘取得的尖锐等周不等式,证明基于Brendle-Eichmair的最优传输方法。

AI中文摘要:

我们证明了欧几里得空间中一类varifolds的Michael-Simon不等式,该类包含所有具有任意维数和余维数的局部有界一阶变分的积分varifolds。在余维数$2$的情况下,该不等式是尖锐的,并蕴含了varifolds的尖锐等周不等式,其等号恰好在圆盘上取得。我们的证明使用了Brendle-Eichmair的最优传输方法。

英文摘要:

We prove a Michael-Simon inequality for a class of varifolds in Euclidean space that includes all integral varifolds with locally bounded first variation of arbitrary dimension and codimension. In codimension $2$, this inequality is sharp and implies the sharp isoperimetric inequality for varifolds, which attains equality precisely for the round disk. Our proof uses the optimal transportation approach of Brendle-Eichmair.
