Oct 29, 2020 at 15:18 | comment | added | Ronnie Brown | I'd be interested in mathematical reasons why this was marled down as I am writing an article on negative reactions, apparently, to letting students know of a generalisation of a standard theorem. I suspect it is because homotopy groups are defined only for spaces with one base point. | |
