Abstract
We present an asymptotically exact solution of the Hubbard model at a special interaction strength corresponding to the strong-coupling Fermi-liquid fixed point. This solution is intimately related to the Toulouse limit of the single-impurity Kondo model and the symmetric Anderson model in its strong-coupling limit.
