Collared and non-collared manifold boundaries
arXiv:2003.12000 · doi:10.4171/LEM/1024
Abstract
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.
