By deploying dense subalgebras of l(G) we generalize the Bass conjecture in terms of Connes’ cyclic homology theory. In particular, we propose a stronger version of the l-Bass Conjecture. We prove that hyperbolic groups relative to finitely many subgroups, each of which posses the polynomial conjugacy-bound property and nilpotent periodicity property,(More)
The property that the polynomial cohomology with coefficients of a finitely generated discrete group is canonically isomorphic to the group cohomology is called the (weak) isocohomological property for the group. In the case when a group is of type HF∞, i.e. that has a classifying space with the homotopy type of a cellular complex with finitely many cells(More)
