The current Wikipedia article on Manifolds says that:
I'm confused by the third statement as I would have thought that the half-open interval (0,1] and the circle are both connected one-dimensional manifolds but that neither of them are homeomorphic to either the open or closed intervals.
What am I missing?
UPDATE (2005-10-03): Looks like the Wikipedia entry is, in fact, wrong in making the third statement above.
UPDATE: next post
