Schur-Weyl duality for certain infinite dimensional $\rm{U}_q(\mathfrak{sl}_2)$-modules
Abstract
Let be the two-dimensional simple module and be a projective Verma module for the quantum group of at generic . We show that for any , the endomorphism algebra of is isomorphic to the type Temperley-Lieb algebra for an appropriate parameter depending on . The parameter is determined explicitly. We also use the cellular structure to determine precisely for which values of the endomorphism algebra is semisimple. A key element of our method is to identify the algebras as the endomorphism algebras of the objects in a quotient category of the category of coloured ribbon graphs of Freyd-Yetter or the tangle diagrams of Turaev and Reshitikhin.
