| Jun 13, 2019 at 16:53 | comment | added | David Loeffler | @anon That sounds very plausible, + would give a proper context for both the "usual" theory and Milne's treatment of tori; but do you know where this is written down? | |
| Jun 13, 2019 at 12:48 | comment | added | anon | In the definition of Shimura variety, $X$ should be replaced by a set $Y$ with a transitive action of $G(\mathbb{R})$ which is a finite covering of the usual $X$. Pink pointed out that this becomes necessary when considering the boundaries of Shimura vareties (and it would justify Milne's terminology). Probably the whole of the theory will continue to work in this more general context. | |

removed K-hat because I think it's always equal to K-tilde
