Tame Galois realizations of GSp_4(F_l) over Q
Sara Arias-de-Reyna, Núria Vila
In this paper we obtain realizations of the 4-dimensional general symplectic group over a prime field of characteristic as the Galois group of a tamely ramified Galois ext…

Geometric families of 4-dimensional Galois representations with generically large images
Luis Dieulefait, Nuria Vila
We study compatible families of four-dimensional Galois representations constructed in the étale cohomology of a smooth projective variety. We prove a theorem asserting that the im…

On the images of modular and geometric three-dimensional Galois represetations
Luis Dieulefait, Nuria Vila
We address the problem of the determination of the images of three-dimensional geometric and modular Galois representations. In the modular case the existence of these representati…
