摘要：

A systematic approach, which combines renormalization group equations and self-consistent perturbation theory for the dynamical properties of single impurity exchange models (which hitherto were obtained from numerical results or from approximations), analytically furnishes universal quantities like pseudofermion exponents and large effective couplings, depending on the symmetry of the underlying model.
