The weakly special closure conjecture for canonical-lift torsion loci

From papers

Let XC{\mathcal X}_{\mathbb C} be the complex universal abelian variety considered in the paper, let YXCY\subseteq {\mathcal X}_{\mathbb C} be an irreducible subvariety, and let Ψm\Psi_m denote the locus defined earlier in the paper. A subvariety is weakly special when it is a weakly special subvariety in the sense used for the universal abelian variety. Weakly special closure conjecture. If Y(C)ΨmY(\mathbb C)\cap\Psi_m is Zariski dense in YY, then YY is weakly special. The paper has proved the analogous special-subvariety result but leaves this stronger description of the intersections with Ψm\Psi_m as a conjecture.
