Abstract
The twin group on strands is the group generated by with defining relations , if . We find a new instance of semisimple Schur--Weyl duality for tensor powers of a natural -dimensional reflection representation of , depending on a parameter . At the representation coincides with the natural permutation representation of the symmetric group, so the new Schur--Weyl duality may be regarded as a -analogue of the one motivating the definition of the partition algebra.
