Fields of definition of elliptic fibrations on covers of certain extremal rational elliptic surfaces
Victoria Cantoral-Farfán, Alice Garbagnati, Cecília Salgado +2
We study K3 surfaces over a number field which are double covers of extremal rational elliptic surfaces. We provide a list of all elliptic fibrations on certain K3 surfaces tog…

Torsion groups of elliptic curves over quadratic fields
Antonela Trbović
We prove results towards classifying the possible torsion subgroups of elliptic curves over quadratic fields , where is a square-free integer, and o…
