#### Abstract

conformal eld theory. The structure constants of this ring are known to be dimensions of moduli spaces of generalized -functions, the main result is that they can be expressed as matrix elements of Schur functions dened over a noncommutative alphabet. The letters in the alphabet are closely related to Kashiwara's crystal operators of the kth-symmetric tensor product of Uqcsu(n).
