The bounded height conjecture for the open anomalous locus

Let GG be a group variety, and let VGV\subset G be irreducible. Let VoaV^{oa} be the set of points of VV outside the VV-anomalous varieties, and define

BdimV=codimBdimVB,\mathcal{B}_{\dim V}=\bigcup_{\operatorname{codim} B\geq \dim V}B,

where the union is over all algebraic subgroups BB of GG of codimension at least dimV\dim V. Bounded height conjecture. The set VoaBdimVV^{oa}\cap\mathcal{B}_{\dim V} has bounded height. This generalizes the bounded height conjecture of Bombieri, Masser and Zannier and is intended to address the height obstruction in effective proofs of the torsion anomalous and intersection conjectures.
