Period-map conjecture for lattice-polarized weak del Pezzo pairs

About 9 years old · traced to

Fix a smooth elliptic curve CC. Let (X,C,μ)(X,C,\mu) be a marked LL-polarized weak del Pezzo pair of degree dd with anticanonical curve CC. The period target is

Hom⁡(fd⊥/RL,C),\operatorname{Hom}(f_d^{\perp}/R_L,C),

where RLR_L is the root sublattice associated to the lattice polarization LL.

Period-map conjecture. There is a period map from the moduli space of such marked pairs to Hom⁡(fd⊥/RL,C)\operatorname{Hom}(f_d^{\perp}/R_L,C), and this period map is an isomorphism over a dense open set U⊂Hom⁡(fd⊥/RL,C)U\subset\operatorname{Hom}(f_d^{\perp}/R_L,C).

This is a global Torelli-type assertion for marked lattice-polarized weak del Pezzo pairs. The source reports partial results on period points and surjectivity, but leaves the stated generic isomorphism conjectural.
