| May 8, 2021 at 18:59 | comment | added | Nulhomologous | On the other hand one can find explicit equations of the maps from $X_1(N)$ to $X_0(N)$ for very small $N$'s: namely, for $N=3,..,10$ and 12, where all curves involved have genus 0. What values of $N$ are you interested? | |
| May 8, 2021 at 18:46 | comment | added | Nulhomologous | It is not exactly what you want but in the magma package there are explicit equations of the natural maps from $X_0(N)$ to $X_0(M)$ if $M$ divides $N$. magma.maths.usyd.edu.au/magma/handbook/small_modular_curves | |
