| Feb 27, 2016 at 14:27 | comment | added | Todd Trimble | I'd actually like to see this reopened (if Professor Beenakker and GH did not find simple proofs, then it's worth something). The question would be improved by adding just a bit more in the way of motivation or context (e.g., what physics book and where, and what was the discussion about). | |

| Feb 27, 2016 at 10:07 | comment | added | Carlo Beenakker | it's a sum over Matsubara frequencies, so probably arises from the identity $$\int_{-\infty}^\infty f(\epsilon)\tanh \epsilon\,d\epsilon=2\pi i\sum_{p=0}^\infty f[(2p+1)i\pi],$$ which is just the sum over the residues of a contour integral, but I can't quite make it work. | |
