A moduli approach to quadratic Q-curves realizing projective mod p Galois representations
Julio Fernández
For a fixed odd prime p and a representation ρof the absolute Galois group of Q into the projective group PGL(2,p), we provide the twisted modular curves whose rational points supp…

Plane quartic twists of X(5,3)
Julio Fernandez, Josep Gonzalez, Joan-C. Lario
Given an odd representation of the absolute Galois group of Q onto PGL(2,3) and a positive integer N, there exists a twisted modular curve defined over Q whose rational points clas…
