Let $\Omega \subset \mathbb{R}^n$ be open. Let $V, W \subset \Omega$ be bounded open sets with smooth boundary such that $\overline{V}$ is compact and $\overline{V} \subset W$, and $\overline{W}$ is compact and $\overline{W} \subset \Omega$. If $s,t \in \mathbb{R}$ satisfy $s>t$, then the restriction operator
