A note on Jacobians of quasiplatonic Riemann surfaces with complex multiplication

Abstract

Let m ≥slant 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 C22 2 Cm 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.
