| Apr 30, 2020 at 18:20 | comment | added | Will Sawin | Isn't $B_R \cap \mathbb Z= \{0\}$ for $n$ large enough because $|1| = \sqrt{n}$ by this definition? When $n$ is sufficiently large, $B_R \cap \mathcal O_K$ will also be zero by the fact that the norm of a nonzero element of $\mathcal O_K$ is a nonzero integer and the arithmetic-geometric mean inequality. | |
