| Mar 6, 2017 at 12:23 | comment | added | Piotr Achinger | $E[\ell]$ is etale over $\mathbb{Z}$ away from $\ell$ (and primes of bad reduction), so certainly $S_P\cap \{ \text{good primes}\} \subseteq \{\text{primes over }\ell\}$. And you can certainly have equality e.g. if $E$ is supersingular at $\ell$. | |
