Imaginary quadratic number fields with class groups of small exponent

Andreas-Stephan Elsenhans, Jürgen Klüners, Florin Nicolae

Let $D < 0$ be a fundamental discriminant and denote by $E (D)$ the exponent of the ideal class group $Cl (D)$ of $K = Q (D)$ . Under the assumption that no Siegel…

Real and complex multiplication on K3 surfaces via period integration

Andreas-Stephan Elsenhans, Jörg Jahnel

We report on a new approach, as well as some related experiments, to construct families of K3 surfaces having real or complex multiplication. The approach is based on an explicit d…
