[edit] Special name for special function?

Does this function have a special name? --HappyCamper 23:06, 1 January 2008 (UTC)

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)
