论文摘要
我们在此注释中收集了有关不可超歧管的领界或非领界的结果和示例。几乎所有内容都是众所周知的，但在文献中有点分散，其中一些显然根本没有出版。
We gather in this note results and examples about collared or non-collared boundaries of non-metrisable manifolds. Almost everything is well known but a bit scattered in the literature, and some of it is apparently not published at all.
