Explicit p-adic Hodge theory for elliptic curves and non-split Cartan images

Matthew Bisatt, Lorenzo Furio, Davide Lombardo

Let $E / Q_{p}$ be an elliptic curve whose mod $p$ Galois image is contained in the normaliser of a non-split Cartan. We classify the possible $p$ -adic images of $E$ using too…

Explicit open image theorems for abelian varieties with trivial endomorphism ring

Matthew Bisatt, Davide Lombardo

Let $K$ be a number field and $A / K$ be an abelian variety of dimension $g$ . Assuming that the image $G_{ℓ^{\infty}}$ of the natural Galois representation attached to the Tate modu…
