Let W be the Weyl group of G. In this paper we give an explicit realization of the group ring Z[W ] inside the ring of integer valued constructible functions on Z (with multiplication given by convolution). In this realization, Z[W] comes equipped, in addition to its standard basis, with a remarkabl
In this note we give a description of the representation of the wreath product S n [G] of the symmetric group S n and a finite group G on the homology of the product of n copies of a partially ordered set (poset for short) P on which G acts as a group of automorphisms. In the sequel all posets will
