The marked relative GW/PT correspondence

Let (X,D)(X,D) be the relative geometry, let β\beta be a curve class, let λ\lambda be a relative boundary condition, and let γH((X,D)r)\gamma\in H^{\ast}((X,D)^r). The marked descendents τα11ταr1(γ)\tau_{\alpha_1-1}\cdots\tau_{\alpha_r-1}(\gamma) are transformed by the relative descendent correspondence.

The marked relative GW/PT correspondence. For all γH((X,D)r)\gamma\in H^{\ast}((X,D)^r), ZPT,β(X,D)(λτα11ταr1(γ))Z^{(X,D)}_{\mathsf{PT},\beta}(\lambda\mid\tau_{\alpha_1-1}\cdots\tau_{\alpha_r-1}(\gamma)) is the Fourier expansion of a rational function in pp, and under p=ezp=e^z,

ZPT,β(X,D)(λτα11ταr1(γ))=ZGW,β(X,D)(λτα11ταr1(γ)).Z^{(X,D)}_{\mathsf{PT},\beta}(\lambda\mid\tau_{\alpha_1-1}\cdots\tau_{\alpha_r-1}(\gamma))=Z^{(X,D)}_{\mathsf{GW},\beta}(\lambda\mid\overline{\tau_{\alpha_1-1}\cdots\tau_{\alpha_r-1}(\gamma)}).

This extends the relative correspondence from products of pullbacks of individual insertions to arbitrary cohomology classes on (X,D)r(X,D)^r.
