Only harmonic and multiple polylogs take some knowledge to conjugate, the other polylogs could use the default behaviour. Harmonic polylogs can be evaluated everywhere now, so they would need the knowledge of how to cconj themselves.
Now I'm confused. Aren't those harmonic and multiple polylogs analytic?
Me confused too.
I was confused. But now I am not confused anymore. Of course it is analytic and that`s it. What confused me is a bug in the 1/x transformation of the harmonic function in CVS HEAD. It gives wrong results for arguments with positive imaginary part in some cases. I have to debug that. It is probably a good idea to integrate this cconj into the checks and exams of the polylogs ... ;-) Concerning the substitution of cconj(x) with x, if x is a symbol known to be real, I agree with you. It looks like a waste of time. Bye, Jens
