Abstract: We consider families of cyclic covers of the projective line, where we fixthe covering group and the local monodromies and we vary the branch points. Weprove that there are precisely twenty such families that give rise to a specialsubvariety in the moduli space of abelian varieties. Our proof uses techniquesin mixed characteristics due to Dwork and Ogus.
