complex iteration (complex "height")
#19
I tried to do analytically one case:

lower fixed point \( a=\Omega=0.567143.. \)
we get the base by \( b={1/e}=\Omega^{1/\Omega} \)
if \( z={1/\Omega} \) then

\( {1/e}[4]{1/\Omega}=\exp_{1/e}^{\circ 1/\Omega}(1)=\lim_{n\to\infty} \log_{1/e}^{\circ n}(\Omega*(1-\ln(\Omega)^{1/\Omega}) + \ln(\Omega)^{1/\Omega }\exp_{1/e}^{\circ n}(1)) \)

but :


\( \ln(\Omega)=-\Omega \)

\( \ln(\Omega)^{1/\Omega }=({1/\Omega })*\ln(\Omega)={-\Omega/\Omega }=-1 \)

\( {1/e}[4]{1/\Omega}=\lim_{n\to\infty} \log_{1/e}^{\circ n}(\Omega*(1-(-1)) -1*\exp_{1/e}^{\circ n}(1)) \)

\( {1/e}[4]{1/\Omega}=\lim_{n\to\infty} \log_{1/e}^{\circ n}(\Omega*2 -1*\exp_{1/e}^{\circ n}(1)) \)

At this point I do not know what to do with limits -how do You apply n to iterating logarithms, and at the same time to iteration of exponentiation of 1/e inside it? If we could move limit inside, than:

\( \lim_{n\to\infty} \exp_{1/e}^{\circ n}(1))=h({1/e)}=\Omega \)

And \( 2*\Omega-\Omega=\Omega \)

\( \log_{1/e}(\Omega)= \Omega \)

for all n, so

\( {1/e}[4]{1/\Omega}=\Omega \) which equals

\( {\Omega^{1/\Omega}[4]{1/\Omega}=\Omega \)

I know it is not complex but real...

Must be a mistake with the limits, but looks nice still...

If someone could explain me on this example how I should have proceeded after the place where I got to limit taking inside iterated logarithm, I promise never to make the same mistake.

If we take the same but:

\( z={-1/\Omega} \)

Then I have to go through the whole procedure again.
In this case, instead of \( 2*\Omega \) we will have 0, and + before tower as:

\( \ln(\Omega)^{-1/\Omega }=(-{1/\Omega })*\ln(\Omega)={-\Omega/-\Omega }=1 \)

\( {1/e}[4]{-1/\Omega}=\lim_{n\to\infty} \log_{1/e}^{\circ n}(1*\exp_{1/e}^{\circ n}(1)) \)

this seems to equal 1. So with negative height:

\( {1/e}[4]{-1/\Omega}= 1 \)

\( {\Omega^{1/\Omega}[4]{-1/\Omega}=1 \)
