Odd annular Bar-Natan category and gl(1|1) (2206.01892v1)

Abstract: We introduce two monoidal supercategories: the odd dotted Temperley-Lieb category $\mathcal{T!L}{o,\bullet}(\delta)$, which is a generalization of the odd Temperley-Lieb category studied by Brundan and Ellis, and the odd annular Bar-Natan category $\mathcal{BN}{!o}(\mathbb{A})$, which generalizes the odd Bar-Natan category studied by Putyra. We then show there is an equivalence of categories between them if $\delta=0$. We use this equivalence to better understand the action of the Lie superalgebra $\mathfrak{gl}(1|1)$ on the odd Khovanov homology of a knot in a thickened annulus found by Grigsby and the second author.
