Abstract

Let Uq(g)U_q(\mathfrak{g}) be the quantized superalgebra of g=gl(k11)gl(kmm)\mathfrak{g}=\mathfrak{gl}(k_1|\ell_1)\oplus\cdots\oplus\mathfrak{gl}(k_m|\ell_m) and Hm,n(q,Q)H_{m,n}(q,\mathbf{Q}) the cyclotomic Hecke algebra of type G(m,1,n)G(m,1,n). We define a right Hm,n(q,Q)H_{m,n}(q,\mathbf{Q})-action on the nn-fold tensor (super)space of the vector representation of Uq(g)U_q(\mathfrak{g}) and prove the Schur--Weyl reciprocity between Uq(\mathfakg)U_q(\mathfak{g}) and Hm,n(q,Q)H_{m,n}(q,\mathbf{Q}).
