| Aug 1 at 3:25 | comment | added | Karl Schwede | I assume 1. does not hold but I'd have to think hard to find an example. 2. is open outside of when we know resolution of singularities holds (ie, char 0 or dim $\leq 3$). If you can weaken $\pi$ birational to $\pi$ and alteration (I assume you want $\pi$ to be proper/projective) then you can make $Y$ nonsingular. | |
