Bombieri-Masser-Zannier's torsion anomalous openness conjecture

Let GG be a semi-abelian variety and let VV be a weak-transverse variety in GG. Let VtaV^{ta} denote the complement in VV of the union of all VV-torsion anomalous varieties. Bombieri-Masser-Zannier conjecture. The set VtaV^{ta} is a dense open subset of VV. The paper presents this as a stronger conjecture encompassing the torsion openness and torsion finiteness conjectures, and notes that it also specifies that VtaV^{ta} is empty exactly when VV is not weak-transverse.
