Bloch's correspondence conjecture for the Albanese filtration

From papers

Let XX be a smooth projective surface and let YY be a smooth projective variety of dimension dd. Let Aj()A^j(-) denote Chow groups and let FF^\bullet be the filtration on zero-cycles predicted by Beilinson and Murre. Write

GrFγ:GrFAd(Y)GrFA2(X)Gr^*_F\gamma:Gr^*_F A^d(Y)\longrightarrow Gr^*_F A^2(X)

for the map induced by a correspondence γA2(Y×X)\gamma\in A^2(Y\times X), and let cl(γ)H4(Y×X)cl(\gamma)\in H^4(Y\times X) be its cohomology class.

Bloch's conjecture. For every γA2(Y×X)\gamma\in A^2(Y\times X), the induced action GrFγGr^*_F\gamma depends only on cl(γ)cl(\gamma).

This is a correspondence-invariance formulation of Bloch's conjecture, linking the action of algebraic cycles on the graded Chow groups to their cohomology classes. The source derives it from Beilinson's conjectural filtration; the related Albanese-kernel consequence is known in some cases but remains open for complex general-type surfaces with pg=0p_g=0.
