In this paper we investigate the \(\infty \)-capacity and the Faber–Krahn inequality on the Grushin space \({\mathbb {G}}^n_\alpha \). On the one hand we show that the \(\infty \)-capacity equals the limit of the p-th root of the p-capacity as \(p\rightarrow \infty \) and give a simple geometric characterization in terms of the Carnot–Carathéodory distance, on the other hand we establish some basic properties for the \(\infty \)-capacity, \(\infty \)-eigenvalue and the Faber–Krahn inequality on the Grushin space \({\mathbb {G}}^n_\alpha \).

Grushin空间上的$$ \ infty $$∞-容量和Faber-Krahn不等式
在本文中,我们研究了Grushin空间\({\ mathbb {G}} ^ n_ \ alpha \)上的\(\ infty \)-容量和Faber-Krahn不等式。一方面,我们表明,\(\ infty \) -容量等于极限p的第的根p -容量为\(P \ RIGHTARROW \ infty \) ,并给出一个简单的几何特征中的条款卡诺-右端是Carathéodory距离,在另一方面,我们建立一些基本性质为\(\ infty \) -容量,\(\ infty \) -eigenvalue并在格鲁申空间费伯-克拉恩不等式\({\ mathbb {绿}} ^ n_ \ alpha \)。
