分数阶高斯周长的Gamma收敛性

Gamma-convergence of fractional Gaussian perimeter

Alessandro Carbotti, Simone Cito, Domenico Angelo La Manna, Diego Pallara

摘要:

我们证明了重整化分数高斯$s$ -周长的$Γ$ -收敛到高斯周长为$s\to 1^-$ .分数周长的定义来自于由Bochner从属公式给出的Ornstein-Uhlenbeck算子的分数幂的定义。作为高斯设置的一个典型特征,出现在$Γ$限制前面的常数与维数无关。

英文摘要:

We prove the $Γ$-convergence of the renormalised fractional Gaussian $s$-perimeter to the Gaussian perimeter as $s\to 1^-$. Our definition of fractional perimeter comes from that of the fractional powers of Ornstein-Uhlenbeck operator given via Bochner subordination formula. As a typical feature of the Gaussian setting, the constant appearing in front of the $Γ$-limit does not depend on the dimension.
