Rosso and Green have shown how to embed the positive partUq( ) of a quantum enveloping algebraUq( ) in a quantum shuffle algebra. In this paper we study some properties of the image of the dual canonical basisB*ofUq( ) under this embedding Φ. This is motivated by the fact that when is of typeAr, the elements of Φ(B*) areq-analogues of irreducible characters of the affine Iwahori-Hecke algebras attached to the groupsGL(m) over ap-adic field.
