Additional explanation
The previous edit changed the meaning of the lemma and we changed it
back. Then we added some remarks to make sure the proof works.

Equivalence of modifications for G-rings
Finally! As Jason pointed out in
http://math.columbia.edu/~dejong/wordpress/?p=3692&cpage=1#comment-1120289
you can deduce this result from Artin's results on modifications of
algebraic spaces. In fact, it seems likely that his arguments are very
close to those given here, but I haven't checked this.

Coequalizers of some natural equivalence relations
The first result is that if Y ---> X is surjective proper, then
the coequalizer of the two maps Y x_X Y ---> Y exists, is finite over X
and is in fact universally homeomorphic to X.
The second result says something more if Y consists of a blowing up in a
closed disjoint union the closed.
