Abstract

We associate a diagrammatic monoidal category Heisk(A;z,t)\mathcal{H}\textit{eis}_k(A;z,t), which we call the quantum Frobenius Heisenberg category, to a symmetric Frobenius superalgebra AA, a central charge kZk \in \mathbb{Z}, and invertible parameters z,tz,t in some ground ring. When AA is trivial, i.e. it equals the ground ring, these categories recover the quantum Heisenberg categories introduced in our previous work, and when the central charge kk is zero they yield generalizations of the affine HOMFLY-PT skein category. By exploiting some natural categorical actions of Heisk(A;z,t)\mathcal{H}\textit{eis}_k(A;z,t) on generalized cyclotomic quotients, we prove a basis theorem for morphism spaces.
