Can the pre-image of the real points in the complex upper-half plane of a modular elliptic curve under the modular parametrization be identified?
@ChrisWuthrich Ah, of course, thanks |

@ChrisWuthrich Is it easy to see that complex conjugation corresponds to reflection in the imaginary axis? |

Thanks Will! Do I understand correctly that this is what you're saying: you view $E$ as a quotient of the moduli space $X_0(N)$. Then the real locus maps to a real curve on $E(\Bbb C)$ with the property that the imaginary part of the invariant differential vanishes. On $\mathfrak H$ this differential is $2\pi if(\tau)d\tau$ up to a constant factor and the imaginary part of the differential vanishes on curves over which the imaginary part of the modular form is constant. |

Thanks a lot! Indeed the formulation was very unclear, I meant points of $\mathfrak{H}$ corresponding to real points of $X_0(N)$ or mapping to real points of $E$. I edited the question to make it clearer. |
