Abstract

We categorify the action of Uq(gl11)U_q(\mathfrak{gl}_{1|1}) on the tensor product of its vector representations (C11)N(\mathbb{C}^{1|1})^{\otimes N}. The generators EE and FF are represented by Fourier-Mukai functors between the derived categories of coherent sheaves on the total spaces of "semi-parabolic" vector bundles over the Grassmannians Gr(k,N)Gr(k,N).
