For arbitrary Fermionic self energy, \Sigma(i wn) with wn=(2n+1)pi T, its real part is always an even function of wn while its imaginary part is always an odd function of wn.

I'm sorry you are not generating any responses at the moment. Is there any additional information you can share with us? Any new findings?

Sorry, I think the issues about this analytic property of self energy is well known, or easily derived. I was curious why people would not enforce it in their calculation when say they design self energy ansatz for possible analytic continuation.

Or, more specifically, \sigma(iw)=\sigma(-iw)*
