| Jan 12, 2015 at 4:09 | comment | added | Eric Wofsey | It's a disjoint union of the open disk and the open interval. | |
| Jan 11, 2015 at 23:55 | comment | added | Hugo Chapdelaine | Eric, now that I'm thinking about your construction, why do you get a finite disjoint union of open cells? | |
| Jan 11, 2015 at 23:27 | comment | added | Hugo Chapdelaine | Thanks Eric for the instructive exemple. I can now better appreciate the constraints that come with the definition of a (finite) CW complex where the gluing does not affect the open cells but only their boundaries. | |
