Affine $G_2$ Centralizer Algebras

Abstract

We show that ${\rm End}_{\bf U}(V_\lambda\otimes V^{\otimes n})$ is generated by the affine braid group $AB_n$ where ${\bf U}=U_q\mathfrak g(G_2)$, $V$ is its 7-dimensional irreducible representation and $V_\lambda$ is an arbitrary irreducible representation.
