Streszczenie
Let be the quantized enveloping superalgebra of \mathfrak g=\mathfrak{gl}(k_1|\ell_1)\oplus \cdots \oplus \mathfrak{gl}(k_m|\ell_m) and let \mathcal H_{m,n} be the Ariki–Koike algebra. We define a right \mathcal H-action on the n-fold tensor (super) space of the vector representation of U_q(\mathfrak g) and prove Schur–Sergeev duality between U_q(\mathfrak g) and \mathcal H_{m,n}.
