I was wondering if there could be a picture added with reference to the example of the birational equivalence of the projective plane and a quadric. Is it possible to create an intuitive picture of the projection to see where the 'blow ups' happen? Thanks. 72.151.105.202 11:11, 7 September 2006 (UTC)angel

Notation

I suggest a better notation:

$\phi :X{\text{⇢}}Y$
