Abstract

To any Frobenius superalgebra AA we associate an oriented Frobenius Brauer category and an affine oriented Frobenius Brauer category. We define natural actions of these categories on categories of supermodules for general linear Lie superalgebras glmn(A)\mathfrak{gl}_{m|n}(A) with entries in AA. These actions generalize those on module categories for general linear Lie superalgebras and queer Lie superalgebras, which correspond to the cases where AA is the ground field and the two-dimensional Clifford superalgebra, respectively.
