摘要：

We construct the fusion ring of a quasi-rational (sl) over cap (4)(k) WZNW theory at generic k is not an element of Q level. It is generated by commutative elements in the group ring Z[(W) over tilde] of the extended affine Weyl group (W) over tilde, which extend polynomially the formal characters of finite-dimensional representations of sl(4).
