摘要
It is shown that to every Q-linear cycle (alpha)over-bar modulo numerical equivalence on an abelian variety A there is canonically associated a Q-linear cycle a modulo rational equivalence on A lying above (alpha)over-bar, characterised by a condition on the spaces of cycles generated by alpha on products of A with itself. The assignment (alpha)over-bar -> alpha a respects the algebraic operations and pullback and push forward along homomorphisms of abelian varieties.
