Voisin map conjecture for homologically trivial zero-cycles

From papers

Let YY be the variety in the preceding construction and let X=Fr(Y)X=F_r(Y), with r2r\geq 2, where Ψ:XX\Psi:X\dashrightarrow X is the Voisin rational map. For zCH0(X)homz\in CH_0(X)_{hom}, the subgroup of homologically trivial zero-cycles on XX, Voisin map conjecture.

Ψz=(2)r+1z.\Psi_*z=(-2)^{r+1}z.

This conjecture is presented as a consequence of the conjectural structure of zero-cycles on the varieties Fr(Y)F_r(Y); the analogous eigenvalue formula for the holomorphic top form and the degree of Ψ\Psi are established in the paper. Its status is not determined by the supplied text.
