SUMMARY:On smooth projective surfaces over Z
DESCRIPTION:Speaker: Fabio Bernasconi\, Sapienza University of Rome\n\nA folklore question to arithmetic geometry (attributed to Shafarevich and Grothendieck) asks what are the smooth projective varieties of dimension (d) over (\operatorname{Spec}(\mathbb Z)). In relative dimensions (0) and (1), a complete answer is known, thanks to the work of Minkowski, Gauss, and …
