Monodromy groups and exceptional Hodge classes, I: Fermat Jacobians

Andrea Gallese, Heidi Goodson, Davide Lombardo

Denote by the Jacobian variety of the hyperelliptic curve defined by the affine equation over , where is a fixed positive integer. We compu…

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

Matthew Bisatt, Lorenzo Furio, Davide Lombardo

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

On 7-adic Galois representations for elliptic curves over

Lorenzo Furio, Davide Lombardo

In recent years, significant progress has been made on Mazur's Program B, with many authors beginning a systematic classification of all possible images of -adic Galois represen…

Cohomology of varieties over the maximal Kummer extension of a number field

Davide Lombardo, Tamás Szamuely, Tamás Szamuely

Let be a smooth projective geometrically connected variety defined over a number field . We prove that the geometric étale cohomology of with -coe…

Connected monodromy fields of Jacobians with complex multiplication

Andrea Gallese, Davide Lombardo

We describe an algorithm to compute the minimal field of definition of the Tate classes on powers of a Jacobian with potential complex multiplication. This field arises as a na…
