Reciprocity laws à la Iwasawa-Wiles

Francesc Bars, Ignazio Longhi

This paper is a brief survey on explicit reciprocity laws of Artin-Hasse-Iwasawa-Wiles type for the Kummer pairing on local fields.

On Jannsen's conjecture for Hecke characters of imaginary quadratic fields

Francesc Bars

We present a collection of results on a conjecture of Jannsen about the $p$ -adic realizations associated to Hecke characters over an imaginary quadratic field $K$ of class number 1…

The group structure of the normalizer of $Γ_{0} (N)$

Francesc Bars

We determine the group structure of the normalizer of $Γ_{0} (N)$ in $S L_{2} (R)$ modulo $Γ_{0} (N)$ . These results correct the Atkin-Lehner statement at the paper Hecke operators of $Γ_0(…

Galois actions on Q-curves and Winding Quotients

Francesc Bars, Luis Dieulefait

We prove two "large images" results for the Galois representations attached to a degree $d$ Q-curve $E$ over a quadratic field $K$ : if $K$ is arbitrary, we prove maximality of the…
