| Feb 5, 2016 at 1:36 | comment | added | Misha | Yves, this argument is indeed simpler than the one I originally had in mind. I was using Nori's theorem that for infinitely many finite fields $F_p$ the group $\Gamma$ maps to a subgroup between $G(F_p)$ and $G(F_p)^+$, where $G$ is the group scheme of the Zariski closure of $\Gamma$; provided that $\Gamma< GL(N, {\mathbb Q})$. | |
