| May 29, 2022 at 19:38 | comment | added | John Rognes | The Brauer group of $\mathbb{R}$ is $\mathbb{Z}/2$ and the Brauer group of $\mathbb{Q}_p$ is $\mathbb{Q}/\mathbb{Z}$, for each prime $p$, so the `$\mathbb{Z}$' in the question is a typo. The rational quaternion algebra $\mathbb{Q}\{1,i,j,k\}$ maps to the nontrivial element in the Brauer group of $\mathbb{R}$, hence represents a nontrivial class in the Brauer group of $\mathbb{Q}$. | |
