Apr 10, 2022 at 14:43 | comment | added | user471019 | Thanks. Two questions: 1. What is the best known Chebotarev density estimate? 2. Are there better bounds exploiting the fact that $\rho$ is modular? I'm looking for bounds $M$ which one could actually check using a computer. | |
Apr 10, 2022 at 13:57 | comment | added | Ariel Weiss | The representation $\rho$ factors through a finite Galois extension $\mathrm{Gal}(L_f/\mathbb Q)$. The field $L_f$ is unramified outside $Np$ and has degree at most $|\mathrm{GL}_2(\mathbb F)|$ (actually, it's a bit smaller - there are constraints coming from the determinant). So by Hermite-Minkowski, every Galois representation of this shape factors through some $\mathrm{Gal}(L/\mathbb Q)$ where now $L$ depends only on $N$, $p$ and the size of $\mathbb F$. All this can be made explicit, and now you can just apply standard Chebotarev estimates to the extension $L/\mathbb Q$. | |
