The quasi-stabilization mapping-cone conjecture for link Floer complexes

Let Hˉ=(Σ,αˉ,βˉ,wˉ,z,τˉ)\bar{\mathcal H}=(\Sigma,\bar{\boldsymbol\alpha},\bar{\boldsymbol\beta},\bar{\mathbf w},\mathbf z,\bar\tau) be a Heegaard diagram, and let H=(Σ,α,β,w,z,τ)\mathcal H=(\Sigma,\boldsymbol\alpha,\boldsymbol\beta,\mathbf w,\mathbf z,\tau) be its quasi-stabilization. Suppose w2w_2 is the second basepoint, apart from w1w_1, in the component of Σαˉ\Sigma-\bar{\boldsymbol\alpha} containing the curve α1\alpha_1. Suppose τ1(1)={w1}\tau^{-1}(1)=\{w_1\} and τ(w2)=1\tau(w_2)=1, so the variables corresponding to w1w_1 and w2w_2 are U1U_1 and U2U_2, respectively, and w1w_1 is the only basepoint marked by U1U_1. Quasi-stabilization mapping-cone conjecture. For suitable almost complex structures, there is an identification between the Floer complex A(H,s)\mathfrak A^-(\mathcal H,\mathbf s) and the mapping-cone complex

A(Hˉ,s)[[U1]]U1U2A(Hˉ,s)[[U2]].\mathfrak A^-(\bar{\mathcal H},\mathbf s)[[U_1]]\xrightarrow{U_1-U_2}\mathfrak A^-(\bar{\mathcal H},\mathbf s)[[U_2]].

This predicts that quasi-stabilization is represented algebraically by a mapping cone imposing the relation between the variables associated to the two specified basepoints; the source presents it as a conjectural identification for suitable almost complex structures.
