... infinitely many values of r and t, and we use a polynomial argument to complete the proof. The proof of equation (18) is similar to that of (14) using the idea of the proof of (17). We omit the ... calculating the number of sequences in Ω p,r with partial sums S j  1 for all j  1. Since these sequences must start with a “+1,” the number of these sequences equals the n...

We should mention that Bott’s proof, although extremely elegant and unified, is not completely elementary, and more ... elementary proofs of some cases of his theorem have recently appeared in [BB, BE , EE, ER]. We first consider an infinite family of Coxeter systems with linear diagrams. Let W r,s n be th...
