On good reduction of some $$K3$$ surfaces (announcement). (Japanese. English summary) Zbl 1362.14037
Summary: This is an abstract of my talk at RIMS conference on 2011/12/02. The full version of the paper is available at arXiv:1202.2421.
The Néron-Ogg-Shafarevich criterion for abelian varieties tells that whether an abelian variety has good reduction or not can be determined from the Galois action on its $$\ell$$-adic étale cohomology. We show an analogue of this criterion for some special kind of K3 surfaces (those which admit Shioda-Inose structures of product type), which are deeply related to abelian surfaces. We also show a $$p$$-adic analogue.
