| Jun 13, 2012 at 17:12 | comment | added | Ben Wieland | The motivation is to have a local homotopy theoretic characterization of manifolds. All you need to check is the link of points. This doesn't answer the question of why the link of curves is not topologically definable. See my answer, mainly the third paragraph: mathoverflow.net/questions/67458/… | |
