%0 Journal Article %T Complex multiplication, rationality and mirror symmetry for abelian varieties %A Meng Chen %J Mathematics %D 2005 %I arXiv %R 10.1016/j.geomphys.2008.01.001 %X We show that complex multiplication on abelian varieties is equivalent to the existence of a constant rational K\"ahler metric. We give a sufficient condition for a mirror of an abelian variety of CM-type to be of CM-type as well. We also study the relationship between complex multiplication and rationality of a toroidal lattice vertex algebra. %U http://arxiv.org/abs/math/0512470v2
