Ordinary reduction of K3 surfaces

Algebraic Geometry 2009-02-16 v2 Number Theory

Abstract

Let X be a K3 surface over a number field K. We prove that there exists a finite algebraic field extension L/K such that X has ordinary reduction at every non-archimedean place of L outside a density zero set of places.
