Pink's Zilber–Pink conjecture for abelian varieties

Let KK be an algebraically closed field, let AA be an abelian variety defined over KK, and let VV be a subvariety of AA. A subvariety WW of VV is atypical for VV in AA if it is an irreducible component of the intersection of VV with a special subvariety of codimension at least dimVdimW+1\dim V-\dim W+1; it is maximal if it is not contained in any larger atypical subvariety.

Zilber's atypical-intersection conjecture. The subvariety VV contains at most finitely many maximal atypical subvarieties.

This is an unlikely-intersections formulation of the Zilber–Pink conjecture for abelian varieties, and it implies Pink's formulation; the paper uses it as a central conjectural principle. Its status in the stated generality is not specified by the source.
