[edit] manifold??

As far as I can see, the dunce cap has a subset that looks locally like THREE 2-cells joined by a 1-cell, so i don't think this is a manifold. If you only loosely know what "manifold" means, then this might make more sense than something you don't understand at all like, say, algebraic variety, or CW-complex, or stratified manifold, (all of which can describe this kind of space) but nonetheless it should be changed.
