Abelian variety
From Citizendium, the Citizens' Compendium
In algebraic geometry an Abelian variety A over a field K is a projective variety, together with a marked point 0 and two algebraic maps: addition
and inverse
, such that these two maps, and the point 0 satisfy the Abelian group axioms. One dimensional Abelian varieties are elliptic curves. Over the complex numbers Abelian varieties are a subset of the set of complex tori.
