In algebraic geometry an Abelian variety over a field is a projective variety, together with a marked point and two algebraic maps: addition and inverse , such that these two maps, and the point satisfy the Abelian group axioms. One dimensional Abelian varieties are elliptic curves. Over the complex numbers Abelian varieties are as subset of the set of complex tori.
