非原酉反射群G(m, p, n)自然作用于向量空间V = cn。对称群Sk通过置换张量积因子作用于⊗kV。我们证明了在⊗kV上与G(m, p, n)交换的所有矩阵的代数是由Sk和其他三个元素生成的。这是对对称群情况下Jones结果的推广[J]。
Abstract The imprimitive unitary reflection group G(m, p, n) acts on the vector space V =C n naturally. The symmetric group Sk acts on ⊗kV by permuting the tensor product factors. We show that the algebra of all matrices on ⊗kV commuting with G(m, p, n) is generated by Sk and three other elements. This is a generalization of Jones’s results for the symmetric group case [J].
