comment Classical regime for Fermi-Dirac and Bose-Einstein gases
Why do you expect an $\epsilon$-free asymptotic expression? I mean, you can express $\epsilon$ in terms of temperature and density, but to do so you absolutely need the partition function (I think).

comment How can I integrate in $\mathrm{d}t$ the cube of the harmonic oscillator propagator?
@Trimok: One of my approaches was the one you're telling me to follow. The only thing different is that I did an error on calculating the denominator in the third fraction of $\int d \nu_1 d\nu_2 \frac{1}{\nu_1 \pm (\omega-i\epsilon)}\frac{1}{\nu_2 \pm (\omega-i\epsilon)}\frac{1}{\nu_1 + \nu_2 \pm (\omega-i\epsilon)}$ (wow, I did an error in integrating a dirac delta function! maybe I should leave physics). Thank you very much; if you post your comment as an answer I can mark this question as answered. :-)
