Mar 27, 2011 at 14:53 comment added mdeland For your last question, shouldn't this be automatic once you define the cotangent bundles and relative cotangent bundles and show that you have a short exact sequence 0 -> f^*Omega_Y -> Omega_X -> Omega_X/Y -> 0?
Mar 26, 2011 at 20:26 comment added Charles Siegel @Sándor: Yes, the map I have does actually come from a map $\tilde{X}\to \tilde{Y}$.
Mar 26, 2011 at 20:03 comment added Sándor Kovács @Charles: In your last question, do you assume that there is a map between $\overline X$ and $\overline Y$?

$X$ and $Y$ were switched in the formula.
