Representations of quantum toroidal superalgebras and plane $\mathbf{s}$-partitions

Abstract

We construct Fock and MacMahon modules for the quantum toroidal superalgebra $\mathcal{E}_\mathbf{s}$ associated with the Lie superalgebra $\mathfrak{gl}_{m|n}$ and parity $\mathbf{s}$. The bases of the Fock and MacMahon modules are labeled by super-analogs of partitions and plane partitions with various boundary conditions, while the action of generators of $\mathcal{E}_\mathbf{s}$ is given by Pieri type formulas. We study the corresponding characters.
