    • That only small frequencies are involved at low temperature may be seen from dnkF/dβ=- ∫∞dω sech2(βω/2)ω[Aω - A - ω]/4 - ∫∞dω×tanh(βω/2) [dAω/dβ-dA(-ω)/dβ]/2, where Aω=A(kF,ω). The thermal factor in the first term cuts off for ω>T, and the second term only requires that A(kF,ω)=A(kF,-ω) up to frequencies for which there is significant T dependence in A(kF,ω).
