Isogenies between surfaces of the Apéry-Fermi pencil
Marie José Bertin, Odile Lecacheux
Elliptic fibrations of surfaces belonging to the Apéry-Fermi pencil () may have or -torsion sections defining on automorphisms of order or . Fir…
Transcendental lattices of certain singular K3 surfaces
Marie José Bertin, Odile Lecacheux
We compute the transcendental lattices of the singular K3 surfaces belonging to three pencils of K3 surfaces, namely the Apéry-Fermi pencil with transcendental lattice $U\oplus \la…
Some observations about isogenies between surfaces
Marie José Bertin, Odile Lecacheux
Even if there are too many elliptic fibrations to investigate and describe on the singular surface of discriminant 72 and belonging to the Apéry-Fermi pencil ,…
Apéry-Fermi pencil of -surfaces and their -isogenies
Marie José Bertin, Odile Lecacheux
Given a generic surface of the Apéry-Fermi pencil, we use the Kneser-Nishiyama technique to determine all its non isomorphic elliptic fibrations. These computations lead…
Automorphisms of certain Niemeier lattices and Elliptic Fibrations
Marie José Bertin, Odile Lecacheux
Nishiyama introduced a lattice theoretic classification of the elliptic fibrations on a surface. In a previous paper we used his method to exhibit elliptic fibrations, up…
Classifications of elliptic fibrations of a singular K3 surface
Marie José Bertin, Alice Garbagnati, Ruthi Hortsch +4
We classify, up to automorphisms, the elliptic fibrations on the singular K3 surface whose transcendental lattice is isometric to .
