| Feb 7, 2018 at 1:01 | comment | added | Mitchell Faulk | Thanks, Remy. For my purposes I'd really like to take $Y$ to be singular, and let $X$ be a partial resolution of the singularities of $Y$, so that in particular, $f$ is a birational map, but $X$ may still admit singularities itself. | |
| Feb 7, 2018 at 0:47 | comment | added | R. van Dobben de Bruyn | There are definitely situations where the vanishing still holds if $X$ and $Y$ are not smooth. An easy example is when $f$ is flat. But maybe you are interested only in assumptions on $X$ that make this true for every $f \colon X \to Y$ with $Y$ smooth projective (say)? | |
