To quickly assess the difficulty of the text, read a short excerpt:
12) S + g S - a S = xS X XXX X The change in the KS and MM equations is the same as that described for (3. 11), and the discussion of (12) leads in every detail to similar results as were obtained for (1) . The model (1) stands in the relation described in appendix A to the model given by H = 1/2 V a'^a"'"aa, [a, a''"] = 1 The "n-particle distribution function" is p^(6) = [Tr exp(-6H+6yN)] ^Tr{ (a'*')"a" exp(-3H+3tjN) } where N = a a. The generating function is v\ S (x) = I (nl) x^ (6) = p n n=...o + C Trfexp (-eH+3yN)e^^ e^} which is easily calculated to be -43- S (x) = C' I dz{l-exp[3M+ J BV+izCeV)"""'^]} ''" .
