Abstract
A Green's function which is asymptotically exact in the Kondo regime is presented. The temperature-dependent susceptibility of the Anderson model is calculated from this Green's function and is found to be in excellent agreement at all temperatures with the results of renormalization-group theory. The formalism presented suggests a microscopic physical mechanism for the scaling and universality of the thermodynamic properties found in renormalization-group theory.Keywords
