Non-projective K3 surfaces with real or Salem multiplication
Eva Bayer-Fluckiger, Bert van Geemen, Matthias Schütt +1
We determine the Hodge endomorphism algebras of non-projective complex K3 surfaces (and more generally, hyperkähler manifolds). We show that they are either totally real fields or…

K3 surfaces with real or complex multiplication
Eva Bayer-Fluckiger, Bert van Geemen, Matthias Schütt
Let be a totally real number field of degree and let be an integer. We show that if then there exists an -dimensional family of com…
