Imaginary zeros of f(z)= z^(1/z) (real valued solutions f(z)>e^(1/e))
#80
Gottfried Wrote:Ah, yes; that is possibly an interesting question... I'll look at it later.
I think, it should be derivable by an equivalent formula as I had it for purely real bases. Let's see...

Gottfried

Which would lead to fact that those purely imaginary h(s) where s =real>e^(1/e) would have s as superroot (inverse of infinite tetration) of imaginary, as

e^(pi/2) is superroot of +-i, because h(e^(pi/2)) = +-i

Question: How many superroots each of these imaginary values have, and how many of them MUST be real? How are these imaginaries (crossing with imaginary axis of Gottfrieds spiderlike graphs) distributed and why?

I find it very intriguing that superroot of a purely imaginary number can be real.
