Higher-degree local-curve equivariant GW/DT4 conjecture

About 8 years old · traced to

Let CC be a smooth projective curve, let L1,L2,L3L_1,L_2,L_3 be line bundles on CC satisfying

L1⊗L2⊗L3≅ωC,L_1\otimes L_2\otimes L_3\cong\omega_C,

and let d≥1d\geq1. Higher-degree local-curve conjecture. After substituting λ3=−λ1−λ2\lambda_3=-\lambda_1-\lambda_2,

GW0,d[C]=∑k∣d1k3DT4(dk[C])∈Q(λ1,λ2).\mathrm{GW}_{0,d[C]}=\sum_{k\mid d}\frac{1}{k^3}\mathrm{DT}_4\left(\frac{d}{k}[C]\right)\in\mathbb Q(\lambda_1,\lambda_2).

This extends the degree-two local-curve prediction to all positive degrees. It is conjectural in general; the paper reports verification only in limited cases.
