The Links–Quivers Correspondence for rational links

Let LL be a link with ∣L∣|L| components, and let PL⋀j(q,a)P^{\bigwedge^j}_L(q,a) denote its ⋀j\bigwedge^j-colored HOMFLY-PT polynomial. Define

P(L)=∑j≥0(∏i=1j(1−q2i))∣L∣−2PL⋀j(q,a)xj.P(L)=\sum_{j\geq 0}\left(\prod_{i=1}^j(1-q^{2i})\right)^{|L|-2}P^{\bigwedge^j}_L(q,a)x^j.

Let PQ(x‾)P_Q(\overline{x}) be the generating function associated with a symmetric quiver QQ, evaluated at transformed variables x‾\overline{x}. Links–Quivers Correspondence. For every link LL, there is a symmetric quiver QLQ_L such that P(L)P(L) and PQL(x‾)P_{Q_L}(\overline{x}) are equal after a change of variables.

The correspondence relates generating functions of colored HOMFLY-PT polynomials to generating functions, and hence Donaldson–Thomas invariants, of symmetric quivers. The source presents this formulation as the standard Links–Quivers Correspondence and indicates that it will be given a new geometric interpretation for rational links; its resolution status is not specified here.
