Invariants of limit key polynomials
Maria Alberich-Carramiñana, Alberto F. Boix, Julio Fernández +3
Let be a valuation of arbitrary rank on the polynomial ring with coefficients in a field . We prove comparison theorems between MacLane-Vaquié key polynomials for val…
The automorphism group of the non-split Cartan modular curve of level 11
Valerio Dose, Julio Fernández, Josep González +1
We derive equations for the modular curve associated to a non-split Cartan subgroup of . This allows us to compute the automorphism g…
Residual ideals of MacLane valuations
Julio Fernández, Jordi Guàrdia, Jesús Montes +1
Let be a field equipped with a discrete valuation . In a pioneering work, S. MacLane determined all valuations on extending . His work was recently reviewed and ge…
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…
