| Dec 28, 2012 at 17:18 | comment | added | David C | I should have said that normal in the topological sense does not imply normal in the algebraic sense. The only thing we can say is that the cuspidal curve is topologically normal thus homeomorphic to its algebraic normalization. | |
| Dec 28, 2012 at 16:56 | comment | added | Jim Bryan | I'm confused about the case of a cuspidal curve. Isn't the link of the singularity of $y^2=x^3$ the trefoil knot? This is not normal, but the link seems to be connected. What am I missing? | |
