Fixed some typos, reordered the *EDIT*
Nov 12, 2010 at 14:22 comment added user5117 Of course you're right; for some reason when I read "K_{Y/Z} > 0" I interpreted it as "K_{Y/Z} is numerically positive". In retrospect, I have no idea why...

Nov 12, 2010 at 14:17 comment added Karl Schwede I don't think so, am I being dumb for some reason? If I blow up a point on ${\mathbb A}^2=X$, obtaining $f:{\widetilde{X}} \to X$, then $K_{\widetilde X}−f^*K_X=K_{\widetilde{X}/X}= $+1 copy of the exceptional divisor.
