Non-split Cartan curves and a characterization of fake elliptic curves

Enric Florit

The -adic Tate module of an abelian surface with quaternionic multiplication (QM) decomposes as two copies of a two-dimensional -rational representation. To this…

On inertial types of elliptic curves

Jose Castro-Moreno, Enric Florit, Nuno Freitas

We classify the inertial Weil-Deligne types arising from elliptic curves over all finite extensions . Based on this classification, we give a fully explicit descript…

K-varieties and Galois representations

Enric Florit, Ariel Pacetti

In a remarkable article Ribet showed how to attach rational -dimensional representations to elliptic -curves. An abelian variety is a (weak) -variety if it i…

Abelian varieties genuinely of -type

Francesc Fité, Enric Florit, Xavier Guitart

A simple abelian variety defined over a number field is called of -type if there exists a number field of degree which is a subalgebra of $\math…

Abelian varieties that split modulo all but finitely many primes

Enric Florit

Let be a simple abelian variety over a number field such that is noncommutative. We show that splits modulo all but finitely many primes of .…

An atlas of the Richelot isogeny graph

Enric Florit, Benjamin Smith

We describe and illustrate the local neighbourhoods of vertices and edges in the (2, 2)-isogeny graph of principally polarized abelian surfaces, considering the action of automorph…
