By properties, I mean such as linearity, shifting, commutativity, etc.
I was hoping to evaluate something like
$S_\eta = \dfrac{1}{\beta}\displaystyle\sum_{i\omega} g(i\omega)$,
where $g(i\omega) = \dfrac{i\omega-\xi_1}{((i\omega-\xi_2)^2-\xi_3^2)((i\omega-\xi_4)^2-\xi_5^2)}$$$S_\eta = \dfrac{1}{\beta}\displaystyle\sum_{i\omega} \dfrac{i\omega-\xi_1}{[(i\omega-\xi_2)^2-\xi_3^2][(i\omega-\xi_4)^2-\xi_5^2]}$$
by using the results in this table. If not, would it be best to use partial fraction decomposition or is there another method?
