Nontrivial difference sets in groups of order a power of 2 are part of the family of difference sets called Hadamard difference sets. In the abelian case, a group of order 2 2 tq2 has a difference set if and only if the exponent of the group is less tq 2 Ε½ than or equal to 2 . In a previous work R.

Let W be a Coxeter group and let Gw be the associated Artin group. We consider the local system over k(Gw, 1) with coefficients in R = Z[q, q-l] which associates to the standard generators of Gw the multiplication by q. For the all list of finite irreducible Coxeter groups we calculate the top-cohom
