Stratum logarithmic GW/PT correspondence
Let be a toric threefold pair, let be a curve class, let be a vector of partitions, and let be a stratum class, where is a cone, is an equivariant cohomology class, and is an equivariant cohomology class on the corresponding evaluation stratum. Let be the anti-canonical degree of , and write and for the length and size of the th partition. Stratum GW/PT correspondence. The series
is the Laurent expansion of a rational function in . Under ,
This extends the primary logarithmic GW/PT correspondence to stratum invariants, including the non-exotic and exotic classes introduced through subdivisions. The source presents this as a strata conjecture; no resolution status is supplied in the provided text.
