Examples of $K3$ surfaces with real multiplication

Algebraic Geometry 2014-08-13 v2

Abstract

We construct explicit examples of K3K3 surfaces over Q{\mathbb Q} having real multiplication. Our examples are of geometric Picard rank 16. The standard method for the computation of the Picard rank provably fails for the surfaces constructed.
