We solve several low temperature problems of an infinite range metailic spin glass model. A compensation problem of T-0 divergencies is solved for the free energy which helped to extract the quantum critical behaviour of the spin glass order parameters as a function of J-J,(T= 0). The critical value

The vertex corrections of the dynamical spin susceptibility are calculated for a Hubbard model with intermediate coupling strength (U/t --7) and a Fermi surface approximating that of YBa2Cu307. The resulting q-dispersion of the coupling J(q) yields below T¢ for d~2\_y2-wave pairing a resonant-like p
