Partition-function quiver description for equal-sign Hopf link conormal fillings

Let LstL_{st} be a Lagrangian filling of the Hopf link conormal, with s,t{l,m,d}s,t\in\{l,m,d\} and s=t|s|=|t|. Let ZLst{\mathsf{Z}}_{L_{st}} denote its skein-valued partition function, and let Ψdi(0){\mathsf{\Psi}}_{\mathrm{di}}^{(0)}, Ψdi(1)[a2]{\mathsf{\Psi}}_{\mathrm{di}}^{(1)}[a^2], Ψan(1,1){\mathsf{\Psi}}_{\mathrm{an}}^{(-1,-1)}, and Ψan(0,0)[a2]{\mathsf{\Psi}}_{\overline{\mathrm{an}}}^{(0,0)}[a^2] be the basic disk and annulus partition functions associated with the curves in the corresponding quiver description. Equal-sign filling partition-function conjecture. The partition function ZLst{\mathsf{Z}}_{L_{st}} is generated by two basic disks on each Lagrangian component and two basic annuli that differ by a factor of a2a^2. In particular, ZLl+l+{\mathsf{Z}}_{L_{l^{+}l^{+}}} is obtained by inserting Ψdi(0){\mathsf{\Psi}}_{\mathrm{di}}^{(0)}, Ψdi(1)[a2]{\mathsf{\Psi}}_{\mathrm{di}}^{(1)}[a^2], Ψan(1,1){\mathsf{\Psi}}_{\mathrm{an}}^{(-1,-1)}, and Ψan(0,0)[a2]{\mathsf{\Psi}}_{\overline{\mathrm{an}}}^{(0,0)}[a^2] along the curves in the quiver description. This conjectural quiver description gives a proposed explicit form for the skein-valued partition functions of the equal-sign fillings; detailed formulas are provided in the source paper.
