Abstract: A reduction procedure is proposed for the s-d exchange Hamiltonian H describing the interaction of conducting electrons with magnetic impurities in a nonmagnetic host metal. The momenta of interacting electrons are restricted to a thin layer around the Fermi wave number. The reduced Hamiltonian Hr is asymptotically equivalent in the thermodynamic limit to an electron gas decoupled from the impurity spins and exhibits a second order phase transition. The electron spins align antiparallel to those of the impurities below Tc. The presence of a phase transition in Hr proves the existence of transition in H. Kondo's perturbation theory technique is then applied to the interaction H - Hr, yielding a finite resistivity at T = 0.
