Categorical DT MNOP/PT comparison conjecture

About 7 years old · traced to

Let In(X,β)I_n(X,\beta) and Pn(X,β)P_n(X,\beta) be the MNOP and stable-pair moduli spaces, respectively, and let DTC∗(−)\mathcal{DT}^{\mathbb{C}^{\ast}}(-) denote their C∗\mathbb{C}^{\ast}-equivariant categorical DT theories. Categorical DT MNOP/PT comparison conjecture. There exists a fully faithful functor

DTC∗(Pn(X,β))↪DTC∗(In(X,β)).\mathcal{DT}^{\mathbb{C}^{\ast}}(P_n(X,\beta))\hookrightarrow\mathcal{DT}^{\mathbb{C}^{\ast}}(I_n(X,\beta)).

This is the categorical analogue of the d-critical flip relating the MNOP and stable-pair moduli spaces; the source does not give a resolution.
