Density in $W^{s, p} (Ω; N)$

Haïm Brezis, Petru Mironescu

Let $Ω$ be a smooth bounded domain in $R^{n}$ , $0\textless{}s\textless{}\infty$ and $1\le p\textless{}\infty$. We prove that $C^{\infty} (Ω; S^{1})$ is den…

BMO-type norms related to the perimeter of sets

Luigi Ambrosio, Jean Bourgain, Haim Brezis +1

In this paper we consider an isotropic variant of the $B M O$ -type norm recently introduced by Bourgain, Brezis and Mironescu. We prove that, when considering characteristic function…
