Maulik–Nekrasov–Okounkov–Pandharipande relative GW/DT correspondence

Let XX be a smooth projective threefold with a smooth divisor DD, let βH2(X,Z)\beta\in H_2(X,\mathbb{Z}), and let η\eta be a relative partition. Write Z~X/DGW\widetilde{\mathsf{Z}}^\mathrm{GW}_{X/D} and Z~X/DDT\widetilde{\mathsf{Z}}^\mathrm{DT}_{X/D} for the reduced relative Gromov–Witten and Donaldson–Thomas partition functions, and set d:=βc1(X)d:=\int_\beta c_1(X). Maulik–Nekrasov–Okounkov–Pandharipande relative correspondence. Under the change of variables exp(iu)=q\exp(\mathrm{i}u)=-q, one has

(iu)d+(η)ηZ~X/DGW(u,i=1nτ0(γi))β,η=(q)d/2Z~X/DDT(q,i=1nτ~0(γi))β,η.(-\mathrm{i}u)^{d+\ell(\eta)-\lvert\eta\rvert}\widetilde{\mathsf{Z}}^\mathrm{GW}_{X/D}\left(u,\prod_{i=1}^n\tau_0(\gamma_i)\right)_{\beta,\eta}=(-q)^{-d/2}\widetilde{\mathsf{Z}}^\mathrm{DT}_{X/D}\left(q,\prod_{i=1}^n\tilde\tau_0(\gamma_i)\right)_{\beta,\eta}.

This is the relative primary-field GW/DT correspondence; the source does not provide evidence resolving it in the stated generality.
