论文摘要
我们表明，每个拓扑n-manifold M都承认本地封闭的嵌入$ b \ colon m \ hookrightArrow \ mathbb {r}^{2n+1} $，并且是某些社区$ u \ u \ subseteq \ subseteq \ mathbb {r}^r}^{2n+1} $的缩回
We show that every topological n-manifold M admits a locally flat closed embedding $ι\colon M \hookrightarrow \mathbb{R}^{2n+1}$ and is a retract of some neighbourhood $U \subseteq \mathbb{R}^{2n+1}$
