A note on Jacobians of quasiplatonic Riemann surfaces with complex multiplication

Algebraic Geometry 2021-05-06 v2 Number Theory

Abstract

Let m6m \geqslant 6 be an even integer. In this short note we prove that the Jacobian variety of a quasiplatonic Riemann surface with associated group of automorphisms isomorphic to C222CmC_2^2 \rtimes_2 C_m admits complex multiplication. We then extend this result to provide a criterion under which the Jacobian variety of a quasiplatonic Riemann surface admits complex multiplication.
