The generalized-quiver partition-function conjecture for HOMFLY-PT homology

Let KK be a knot with conormal LKL_K in the resolved conifold. Suppose the associated symmetric generalized quiver has nodes 1,,m1,\dots,m, multiplicities μi\mu_i, adjacency matrix CijC_{ij}, disk homology classes μilogx+ailoga\mu_i\log x+a_i\log a, and invariant self-linkings qiq_i. Define the node variables by

xi=xμiqqiCiiμiaai(t)Ciiμi.x_i=x^{\mu_i}q^{q_i-C_{ii}\mu_i}a^{a_i}(-t)^{C_{ii}\mu_i}.

Generalized-quiver partition-function conjecture. After this substitution, the generalized-quiver partition function equals the generating function of Gromov-Witten invariants counting generalized holomorphic curves, equivalently the generating function of symmetrically colored HOMFLY-PT polynomials of KK, and the refined generalized-quiver partition function equals the generating function of Poincaré polynomials of HOMFLY-PT homology in symmetric representations. This is the paper's main conjectural correspondence between generalized quivers, holomorphic-curve counts, and HOMFLY-PT homology; the source gives no resolution evidence.
