| Oct 4, 2016 at 6:56 | comment | added | David Loeffler | I don't think this answers the question, because this argument will only work if R embeds in $\mathbf{C}$. The question makes perfect sense if $R = \mathbf{F}_p$ with $p \nmid N$, for instance (and that sort of example is of fundamental importance in Mazur's work which the OP cites). | |
