Links–Gould invariant conjecture for braided exterior algebras

Let VV be a vector space of dimension NN, let ρ\rho be the RR-matrix-induced structure on the braided exterior algebra [...].[...]. For a long knot, let JρJ_{\rho} denote the associated invariant. Links–Gould invariant conjecture. The invariant has the form

Jρ=LG(N) ⁣(p,t)idΛp(V),J_{\rho}=\operatorname{LG}^{(N)}\!(p,t)\operatorname{id}_{\Lambda_p(V)},

where LG(N) ⁣(p,t)\operatorname{LG}^{(N)}\!(p,t) is the Links–Gould invariant associated with a 2N2^N-dimensional representation of the super quantum group Uq(gl(N1))U_q(\mathfrak{gl}(N|1)). The conjecture identifies the invariants arising from these braided exterior-algebra solutions with the Links–Gould invariants; the source gives no resolution beyond the stated formulation.
