Zilber's finite-family conjecture for atypical intersections

Let GG be a complex semi-abelian variety, and let XX be a closed irreducible subvariety of GG. For a closed equidimensional subvariety HH of GG, call an irreducible component YY of XHX\cap H atypical if

dim(Y)>dim(X)+dim(H)dim(G).\dim(Y)>\dim(X)+\dim(H)-\dim(G).

Zilber's conjecture. There is a finite family Φ\Phi of proper algebraic subgroups of GG such that, for every algebraic subgroup HH of GG, every atypical component of XHX\cap H is contained in one of the members of Φ\Phi.

The conjecture predicts uniform control of all atypical intersections by finitely many proper algebraic subgroups. It is motivated by Zilber's work on the analogue of Schanuel's conjecture in differential fields and is part of the theory of unlikely intersections.
