Logarithmic GW/PT correspondence for primary insertions
Logarithmic GW/PT correspondence for primary insertions
Let be a toric threefold pair, let be a curve class, let be a vector of partitions, and let be an insertion. Write for the anti-canonical degree of , and let and denote the length and size of the th partition. GW/PT correspondence. The PT series is the Laurent expansion of a rational function. Under , one has
This is the logarithmic GW/PT correspondence for primary insertions, asserting both rationality of the PT series and equality with the GW series after the specified change of variables and normalization. The source identifies it as a conjecture previously formulated as Conjecture A; the present paper proves the correspondence for equivariant toric threefold pairs.
