Albanese Variety


The Albanese variety is an Abelian variety canonically attached to an algebraic variety which is the solution to a certain universal problem. The Albanese variety is dual to the Picard variety.

For a smooth connected projective complex surface S, the Albanese homomorphism from the integral degree-zero Chow group to Alb(S)(C) is surjective. Bloch's conjecture predicts that it is an isomorphism when h^0(S,K_S)=0. When also h^1(S,O_S)=0, the Albanese variety is a point and the conjecture predicts that the degree map identifies the integral zero-cycle Chow group with Z (Auel and Bernardara 2017, p. 232).
