Pink's Zilber–Pink conjecture for semiabelian varieties

About 15 years old · traced to

Let G/CG/\mathbb{C} be a semiabelian variety, and for a positive integer mm let G[m]G^{[m]} denote the union of the complex points of all subgroups of GG of codimension at least mm. Let X/CX/\mathbb{C} be a subvariety of dimension dd of GG, and suppose that XX is not contained in a proper abelian subgroup of GG.

Pink's conjecture. The intersection

X∩G[d+1]X\cap G^{[d+1]}

is not Zariski dense.

This is a semiabelian-variety case of the broader Zilber–Pink conjecture, which includes Mordell–Lang and André–Oort as special cases. The source supplies no resolution evidence for this formulation, so it remains open.
