Abstract
The spin and charge susceptibilities of the Wolff model with electron-hole symmetry and the Lorentzian density of band states are obtained exactly by standard perturbation theory. The solution is valid for any value of the Coulomb interaction and exhibits features which are observed experimentally in some strongly-interacting-fermion systems.Keywords
