M | @DavidLoeffler I think that we do not even need something as strong as Ertl–Shiho: the p-completion of integral Monsky–Washnitzer cohomology seems to be crystalline cohomology, thus it is not f.g even for the affine line. Ertl–Shiho is analyzing its image in rigid cohomology, which is subtler. | |

| Feb 25, 2021 at 20:07 | comment | added | David Loeffler | I think it's known that integral MW cohomology is definitely not fg in general, because it agrees (I believe) with integral de Rham--Witt cohomology, and there are explicit examples due to Ertl and Shiho where finite generation of this cohomology fails: doi.org/10.2748/tmj/1601085622 | |
