$\mathfrak{gl}(1|1)$-Alexander polynomial for $3$-manifolds

Abstract

As an extension of Reshetikhin and Turaev's invariant, Costantino, Geer and Patureau-Mirand constructed $3$-manifold invariants in the setting of relative $G$-modular categories, which include both semisimple and non-semisimple ribbon tensor categories as examples. In this paper, we follow their method to construct a $3$-manifold invariant from Viro's $\mathfrak{gl}(1|1)$-Alexander polynomial. We take lens spaces $L(7,1)$ and $L(7,2)$ as examples to show that this invariant can distinguish homotopy equivalent manifolds.
