If s E S is not special, it is still true that Q n Y, is non-empty; however, it may be a union of several left cells. ## 2. NOTATION AND RECOLLECTIONS 2.1. We refer to [l] for the definition of the basis (C,) of the Hecke algebra of ( W, S) and of the relation y< w on W. We shall write y -w instea
The aim of the present paper is to give an explicit description for all the left cells of the Weyl group W of type E 8 . We first find a representative set for the left cells of W and then use it to describe these cells. Our results show that most of the left cells in W can be characterized by their
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 th
