comment Can derivative of Hurwitz Zeta be expressed in Hurwitz Zeta?
@O.L. I would be OK even if it deals with a particular $q$.

Well, yes, but I am interested in exact relations...

@Jean-Claude Arbaut are there anywhere tables of this operator applied to elementary functions? What are the rules for dealing with this operator except linearity?

@MJD particularly, I have encountered a list of when this operator was applied to some functions involving digamma en.wikipedia.org/wiki/… and wondered if this can be re-written in form of antidifferences en.wikipedia.org/wiki/…

@MJD does it mean this linear operator cannot be expressed in terms of antidifference operator?

Thanks! But actually I need the solution for the sum, I just thought it is the same as for the integral...

comment Is there a continuous function on R such that $f(f(x))=e^{-x}$?
This is only if f required to be real-valued. If it is allowed being complex-valued (but continuous and defined on R), it can exist.
