Title: Blowing down, blowing up: surface geometry Abstract:A big question in algebraic geometry is how much one can change a variety without affecting it `generically'. See for example Hartshorne, Algebraic Geometry, Chapter … Otherwise, either X ˘=P2 or there is a morphism X !C where dimC = 1 and the bers are rational curves. In over words, X is the blow up of X 1 at P. We repeat this procedure X !X 1!X 2! People learning it for the first time, would see a lot of algebra, but not much geometry. In general, if I have a curve tangent to the locus that I'm blowing up, where does its "direction" go if the exceptional locus parametrize only normal directions?
