The multiset partition algebra

Video File: 
Abstract: 
We define a new class of diagram algebras MP_λ(n) indexed by integer partitions λ. When λ is a partition of k, MP_λ(n) is isomorphic to a subalgebra of the partition algebra P_k(n) defined by Jones and Martin. When λ = (1^k), MP_λ(n) is isomorphic to P_k(n). A basis of MP_λ(n) is given in terms of certain bipartite multigraphs. We exhibit a new Schur-Weyl duality between the actions of MP_λ(n) and the symmetric group S_n on the symmetric power Sym^λ(C^n). This is joint work with Sridhar Narayanan and Shraddha Srivastava.
