On the geometry of K3 surfaces with finite automorphism group and no elliptic fibrations
Xavier Roulleau
Nikulin and Vinberg proved that there are only a finite number of lattices of rank that are the Néron-Severi group of projective K3 surfaces with a finite automorphism gro…

Explicit Nikulin configurations on Kummer surfaces
Xavier Roulleau, Alessandra Sarti
A Nikulin configuration is the data of disjoint smooth rational curves on a K3 surface. According to results of Nikulin, the existence of a Nikulin configuration means that th…

The Bolza curve and some orbifold ball quotient surfaces
Vincent Koziarz, Carlos Rito, Xavier Roulleau
We study Deraux's non arithmetic orbifold ball quotient surfaces obtained as birational transformations of a quotient of a particular Abelian surface . Using the fact that $…
