- Albanese_variety abstract "In mathematics, the Albanese variety A(V), named for Giacomo Albanese, is a generalization of the Jacobian variety of a curve, and is the abelian variety generated by a variety V taking a given point of V to the identity of A. In other words there is a morphism from the variety V to its Albanese variety A(V), such that any morphism from V to an abelian variety (taking the given point to the identity) factors uniquely through A(V). For complex manifolds Blanchard (1956) defined the Albanese variety in a similar way, as a morphism from V to a torus A(V) such that any morphism to a torus factors uniquely through this map. (It is an analytic variety in this case; it need not be algebraic.)For compact Kähler manifolds the dimension of the Albanese is the Hodge number h1,0, the dimension of the space of differentials of the first kind on V,which for surfaces is called the irregularity of a surface. In terms of differential forms, any holomorphic 1-form on V is a pullback of translation-invariant 1-form on the Albanese, coming from the holomorphic cotangent space of Alb(V) at its identity element. Just as for the curve case, by choice of a base point on V (from which to 'integrate'), an Albanese morphism is defined, along which the 1-forms pull back. This morphism is unique up to a translation on the Albanese.For varieties over fields of positive characteristic, the dimension of the Albanese variety may be less than the Hodge numbers h1,0 and h0,1 (which need not be equal). To see the former note that the Albanese is dual to the Picard variety whose tangent space at the identity is given by . That is a result of Igusa in the bibliography.".
