| Mar 11 at 14:23 | comment | added | user122877 | When $\dim(X)=1$, how exactly does the finiteness of $\text{Br}(X)$ follow from the ABHN theorem? My understanding of ABHN is the short exact sequence $0\to\text{Br}(K)\to\bigoplus_v \text{Br}(K_v)\to\mathbb{Q}/\mathbb{Z}\to0$ for a global field $K$. | |

| Nov 25, 2017 at 4:51 | comment | added | user95222 | @Timo Keller What motivates your question? The question is wide open in the flat proper case over $\text{Spec}(\mathbf{Z})$ as much as in the proper case over $\text{Spec}(\mathbf{Z})$, so you must have something specific in mind. | |

| Nov 7, 2017 at 15:17 | comment | added | Will Sawin | Doesn't the same cohomological argument work? | |
| Nov 7, 2017 at 15:07 | comment | added | user19475 | @WillSawin: This is at least equivalent for function fields. | |
| Nov 7, 2017 at 15:05 | comment | added | Will Sawin | For an elliptic curve, isn't this equivalent to finiteness of Sha, and thus aren't there partial results coming from the various partial results on BSD? | |
