Abstract: In 2006, Oleg Viro studied two interpretations of the (multivariable) Alexander polynomial understood as a quantum link invariant: either by considering the quasitriangular Hopf algebra associated to $ U_q{\mathfrak{sl}(2)}$ at fourth roots of unity, or by considering the super Hopf algebra $ U_q\mathfrak{gl}(1\vert 1)$. In this paper, we show these Hopf algebras share properties with the $ -1$ specialization of $ U_q\mathfrak{gl}(n\vert 1)$ leading to the proof of a conjecture by David De Wit, Atsushi Ishii and Jon Links on the Links-Gould invariants.
