N2 - We present a bosonized action for the SU(N) Kondo problem within the framework of path-integral non-abelian bosonization. We show that the model is equivalent to a level k = 2N + 1 Wess-Zumino-Witten theory coupled to impurity fields. We show that the system is scale invariant in the strong-coupling limit by explicit computation of the β-function. We calculate the magnetic susceptibility and the low-temperature specific heat in the same limit.
