13. N′C. From this definition, the self-energy may be defined as the first functional derivative, and the irreducible vertices as the second functional derivative.
14. Note that in some definitions of the local moment, the prefactor S(S+1) is omitted.
15. The relatively high temperature used here avoids instabilities at lower temperatures.
