| Feb 16, 2022 at 23:13 | comment | added | Jason Starr | There was an approach by Emmy Noether that depended on rationality (over $\mathbb{Q}$) of some quotients of affine space by finite group actions. However, it was proved by Saltman (and Bogomolov, et al.) that some of these quotients are not rational (in fact, not even stably rational). | |
