Actually the corollary works over Dedekind domains (like $\mathbb{Z}[1/2]$) as well, though I didn't write that up in the paper. | |

| Oct 1, 2016 at 17:42 | comment | added | Will Chen | The answer is yes, but a rigorous proof would be quite complicated. Roughly speaking, you have to use the fact the Tate curve over $\mathbb{Z}((q^{1/2}))[1/2]$ admits a $\Gamma(2)$-structure. | |
