Carnot群中非局部周长的局部极小元和Gamma收敛性

Local minimizers and Gamma-convergence for nonlocal perimeters in Carnot Groups

Alessandro Carbotti, Sebastiano Don, Diego Pallara, Andrea Pinamonti

摘要:

我们证明了卡诺群的半空间的局部极小的一类非局部泛函通常称为非局部周长。此外,在一类Carnot群中,De Giorgi的可求直定理成立,我们提供了一个下界的$Γ$ -limif的重新标度的能量的水平周长。

英文摘要:

We prove the local minimality of halfspaces in Carnot groups for a class of nonlocal functionals usually addressed as nonlocal perimeters. Moreover, in a class of Carnot groups in which the De Giorgi's rectifiability Theorem holds, we provide a lower bound for the $Γ$-liminf of the rescaled energy in terms of the horizontal perimeter.
