| Mar 21, 2011 at 18:18 | comment | added | Charles Staats | Once you have enough scheme-theoretic machinery, there's an almost trivial proof that the nonsingular points of a variety form a dense open subset; see III.4 Prop. 3 of Mumford's Red Book, or Hartshorne Corollary II.8.16. The basic idea is to show that, in an appropriate sense, the variety is nonsingular at its generic point. | |
