چکیده
The construction of the fusion ring of a quasi-rational CFT based on sl(3) k at generic level k ∈ Q is reviewed. It is a commutative ring generated by formal characters, elements in the group ring Z[ ˜ W ] of the extended affine Weyl group˜W of sl(3) k. Some partial results towards the sl(4) k generalisation of this character ring are presented.

State spaces of $K_0$ groups of some rings
Let $R$ be a ring with the Jacobson radical $J(R)$ and let $picolon Rto R/J(R)$ be the canonical map. Then $pi$ induces an order preserving group homomorphism $K_0picolon K_0(R)to K_0(R/J(R))$ and an affine continuous map $S(K_0pi)$ between the state space $St(R/J(R))$ and the state space $St(R).$ In this paper, we consider the natural affine map $S(K_0pi).$ We give a condition ...
متن کاملRandom Walk in an Alcove of an Affine Weyl Group, and Non-colliding Random Walks on an Interval
Abstract. We use a reflection argument, introduced by Gessel and Zeilberger, to count the number of k-step walks between two points which stay within a chamber of a Weyl group. We apply this technique to walks in the alcoves of the classical affine Weyl groups. In all cases, we get determinant formulas for the number of k-step walks. One important example is the region m > x1 > x2 > · · · > xn ...
متن کاملAbacus Models for Parabolic Quotients of Affine Weyl Groups
We introduce abacus diagrams that describe the minimal length coset representatives of affine Weyl groups in types C̃/C, B̃/D, B̃/B and D̃/D. These abacus diagrams use a realization of the affine Weyl group C̃ due to Eriksson to generalize a construction of James for the symmetric group. We also describe several combinatorial models for these parabolic quotients that generalize classical results in ...
متن کاملOn a Family of Hyperplane Arrangements Related to the Affine Weyl Groups
Let 8 be an irreducible crystallographic root system in a Euclidean space V , with 8+ the set of positive roots. For α ∈8, k ∈Z, let H(α, k) be the hyperplane {v ∈ V : 〈α, v〉 = k}. We define a set of hyperplanes H = {H(δ, 1) : δ ∈ 8+} ∪ {H(δ, 0) : δ ∈ 8+}. This hyperplane arrangement is significant in the study of the affine Weyl groups. In this paper it is shown that the Poincaré polynomial of...
متن کاملWEYL, DEMAZURE AND FUSION MODULES FOR THE CURRENT ALGEBRA OF slr+1 VYJAYANTHI CHARI AND SERGEI LOKTEV
We construct a Poincare-Birkhoff–Witt type basis for the Weyl modules [CP1] of the current algebra of slr+1. As a corollary we prove the conjecture made in [CP1], [CP2] on the dimension of the Weyl modules in this case. Further, we relate the Weyl modules to the fusion modules defined in [FL] of the current algebra and the Demazure modules in level one representations of the corresponding affin...
