 * $$f_n(z) = \int^\infty_0 \frac{x^n}{ze^x-1} \,dx $$
 * None that I know of, but it can be expressed as $$\Gamma(n+1)\mathrm{Li}_{n+1}\left(\tfrac1z\right)$$ (see Gamma function, Polylogarithm). -- Meni Rosenfeld (talk) 23:13, 1 January 2008 (UTC)
 * Oh, I see. Thank you! --HappyCamper 03:57, 2 January 2008 (UTC)
