I could not sleep because I felt I did not clarify my previous posts enough.
The point is I showed that the first 2 logaritms do not pose a problem.
However the third and fourth logs might be problematic.
With the first 2 logs I was able to " magically " remove the logs , but with ln ln ln ln f( s + 4) this will be pretty hard.
so the 3rd and 4th log might give rise to singularities.
however this does not immediately imply that the limit has a singularity or does it ?
Lets investigate
assume
r(s) = ln^[n] f(s+n) = ln(0)
then r2(s) = ln^[n+1] f(s+n+1) = ln^[n] ( f(s+n) t(s+n) )
For finite n this probably does not equal ln^[n] f(s+n) so it does not follow automatically ...
so those two things ( 3rd and 4th log and r(s), r2(s) ) kept me awake.
The situation is still unclear and I have not even considered the "problem" of branches and periodic points etc.
also although ln(0) for a given n might not be an issue , for a larger value of n say m we might also run into log(0) so it does completely resolve things either !!!!
---
So to think better about the branches , I need to formalize.
And that formilazation is just a proposal/conjecture because it might not be the best aka be analytic or equivalent.
f(s+1) = exp( f(s) t(s) )
then
ln f(s+1) = f(s) t(s) = f(s + h(s))
and
exp( f( s + h(s) ) = f(s+1)
and
f( s + h(s) + 1) = exp( f(s + h(s))) t(s + h(s)) )
therefore
f( s + h(s) + 1)^( t(s+h(s))^{-1} ) = f(s+1).
So the 2 fundamental equations for h(s) are :
f(s) t(s) = f(s + h(s))
and
f( s + h(s) + 1)^( t(s+h(s))^{-1} ) = f(s+1)
In a way we got rid of exp and ln here.
How many solutions h(s) do we get ??
I mentioned h(s) before but then ( i believe ) i only used the first equation. That had many solutions.
how close h(s) is to zero , what branches it implies etc is all closely related ofcourse.
Once we understand h(s) we continue ;
ln ln f(s+2) = ln ( f(s+1) t(s+1) ) = ln( f(s+1 + h(s+1)) ) = f(s+h(s+1)) t(s+h(s+1)) = f( s + h(s+1) + h(s + h(s+1)) ).
And it is clear we can continue "removing" logs with those h's.
the speed of growth of h is ofcourse very important for the convergeance and analyticity of ln^[n] f(s+n) !!
