.

The log is the complex log, which is multiple-valued: , where n is any integer.

And .

Is that what you were asking?

my problem, in its completeness, is the following: i'm looking for singularities of a function whose denominator is . So i look for solutions of . I put where is the principal branch of complex logarithm and by periodicity of complex exp i get , where log in RHS is the real log. So and i was looking for an easy way to write the RHS in order to compute residues at those points

Since and are both real, you can do what I suggested in my previous post:

Other than that, I don't really see how to simplify it.
