Abstract

We introduce two monoidal supercategories: the odd dotted Temperley-Lieb category T ⁣Lo,(δ)\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 BN ⁣o(A)\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 δ=0\delta=0. We use this equivalence to better understand the action of the Lie superalgebra gl(11)\mathfrak{gl}(1|1) on the odd Khovanov homology of a knot in a thickened annulus found by Grigsby and the second author.
