Following the Wiegmann approach the exact expression of the ground state energy for the symmetric Anderson Hamiltonian was obtained. In this paper the calculation is done for the asymmetric Anderson Hamiltonian, of the ground state energy, of the average number of localized electrons and of the charge susceptibility.

This paper proves an important equation for the Anderson model. Then, using this equation we deal exactly with the Anderson model and obtain the exact analytical expression for the ground-state energy. This result coincides with the result of the Bethe ansatz.

In this article the authors examine the analytic structure of the Bethe ansatz solution for the ground state energy of the symmetric Anderson model as a function of the interaction U. They find that the energy is analytic for all real U and examine also the strong coupling limit U to infinity .
