and i pointed out that a periodic function is not a superfunction in the direction of its period.

(Oo, I just deleted that post, I didn't think someone would have gotten to it already... (Just for reference: the post was asking about what "nc" was since I hadn't seen it before, then I looked it up and saw it really does exist and that's why I deleted it))
Yeah, but \( F(z) = \mathrm{cn}(2^z) \) is not periodic in the real axis direction due to the exponential (it does have an imaginary period of \( \frac{2\pi i}{\log(2)} \) but not a real one) It's not straight \( \mathrm{cn} \), but \( \mathrm{cn} \) composed with an exponential.
