| Jan 29 at 10:44 | comment | added | Daniel Loughran | Would it maybe be more natural to consider cohomology with compact supports for non-proper varieties? This is what appears in the Grothendieck-Lefschetz trace formula, for example. | |

| Jan 27 at 12:31 | comment | added | Jason Starr | If there exists a radiciel resolution of singularities (e.g., normalization of a cusp) then the etale cohomology is pure. | |
