Plane quartics over $\mathbb{Q}$ with complex multiplication

Number Theory 2022-04-11 v4 Algebraic Geometry

Abstract

We give examples of smooth plane quartics over Q\mathbb{Q} with complex multiplication over Q\overline{\mathbb{Q}} by a maximal order with primitive CM type. We describe the required algorithms as we go, these involve the reduction of period matrices, the fast computation of Dixmier-Ohno invariants, and reconstruction from these invariants. Finally, we discuss some of the reduction properties of the curves that we obtain.
