Abstract

We study the tensor product algebra Pk(x1)Pk(x2)Pk(xm), where Pk(x) is the partition algebra defined by Jones and Martin. We discuss the centralizer of this algebra and corresponding Schur-Weyl dualities and also index the inequivalent irreducible representations of the algebra Pk(x1)Pk(x2)Pk(xm) and compute their dimensions in the semisimple case. In addition, we describe the Bratteli diagrams and branching rules. Along with that, we have also constructed the RS correspondence for the tensor product of m-partition algebras which gives the bijection between the set of tensor product of m-partition diagram of Pk(n1)Pk(n2)Pk(nm) and the pairs of m-vacillating tableaux of shape [λ]Γkm, Γkm={[λ]=(λ1,λ2,...,λm)|λiΓk,i{1,2,...,m}} where Γk={λit|0tk}. Also, we provide proof of the identity (n1n2nm)k=[λ]Λn1,n2,...,nmkf[λ]mk[λ] where mk[λ] is the multiplicity of the irreducible representation of Sn1×Sn2×....×Snm module indexed by [λ]Λn1,n2,...,nmk, where f[λ] is the degree of the corresponding representation indexed by [λ]Λn1,n2,...,nmk and [λ]Λn1,n2,...,nmk = {[λ]=(λ1,λ2,...,λm)|λiΛnik,i{1,2,...,m}} where Λnik={μ=(μ1,μ2,...,μt)ni|niμ1k}.
