Refined invariant generating-function conjecture for weighted projective planes

From papers

Let Nδ(d,m;y)N_\delta(d,m;y) be the polynomial from the weighted-projective refined node polynomial conjecture, let N~(Σm,dH),δ(y)\widetilde N^{(\Sigma_m,dH),\delta}(y) be the refined invariant on the minimal resolution Σm\Sigma_m, and let DG~2\widetilde{DG}_2 be the refined modular series used as the change-of-variables parameter. Weighted-projective refined generating-function conjecture. There exist power series C1,C2,C3Q[y±1][[q]]C_1,C_2,C_3\in\mathbb Q[y^{\pm1}][[q]] such that

δ0Nδ(d,m;y)(DG~2)δ=(δ0N~(Σm,dH),δ(y)(DG~2)δ)C1(m+2)dC2m+2C3.\sum_{\delta\ge0}N_\delta(d,m;y)(\widetilde{DG}_2)^\delta= \left(\sum_{\delta\ge0}\widetilde N^{(\Sigma_m,dH),\delta}(y)(\widetilde{DG}_2)^\delta\right)C_1^{(m+2)d}C_2^{m+2}C_3.

This conjecture proposes a universal multiplicative correction relating the weighted-projective and resolution-side generating functions.
