I have this non-trivial complex function based on.(adsbygoogle = window.adsbygoogle || []).push({});

[tex]f(E)=\sum_{2,\omega}\frac{h(1,2,\omega)}{E-E_{2}-\hbar\omega+i\delta}[/tex]

So is a sum of this denominator that rises many poles and zeros.

I want to find all the zeros (computationally, analitically, I don't mind) a in a fairly efficient way (that must be done like thousands times, so I cant make a night for one iteration)

If you have any ideas or suggestions I'm all ears
