| May 19, 2023 at 15:18 | comment | added | María | Thank you very much! For $\Gamma_0(N)$ everything is clear to me but for the other congruence subgroup $\Gamma_1(N)$ I do not know how to do the calculation. I thought that maybe it could be analogous to the one I posted but it seems something change or maybe I am misunderstanding something :( | |
