Abstract
We investigate the duality in the Kondo model. Starting from the s-d model with the coupling constant , the strong coupling model with the constant of 1/J is identified. The model shows the unitary limit of the conductance, at zero temperature. The perturbation theory of the model gives qualitative agreement with the results of numerical renormalization group and Bethe ansatz near .
