K3 surfaces and their Picard groups

Jörg Jahnel (Göttingen - Personal website)

The goal of this talk is to report on a project to compute the Picard rank for certain K3 surfaces. The methods are based on reduction modulo p. They will be explained in some detail and examples will be given. At the end of the talk, a statistical test will be presented showing that for each K3 surface in two large samples, suitable primes may be found and the Picard rank may be determined. The samples are motivated by classical families considered by 19th century geometers.
