Number Theory

In this section we generalise results of [DW11] by proving that compatible systems with certain local properties and the global assumption that all (but a density zero set) residual images are huge lead to the realisation of PSpn(Fℓd) or PGSpn(Fℓd) …

Compatible systems of symplectic Galois representations and the inver…

This article is the first part of a series of three articles about compatible systems of symplectic Galois representations and applications to the in…
