For example, if two K3s over a finite field $\mathbb{F}_q$ have isomorphic $H^2_{crys}(X/W(\mathbb{F}_q))$(respect both $\phi$ and cup-product), are these two K3s isomorphic abstractly over $\overline{\mathbb{F}_q}$? (I am aware of a crystalline Torelli for supersingular K3s, so I wonder if a similar thing holds for non-supersingular ones) | |
