tetration bending uniqueness ?
#13
im sorry

i do not wish to be annoying.

but this does not seem like a new idea.

in fact , it seems mine :

quoting from my own posts :

thread tid 474 posted on 7/11/10 title : tommy's uniqueness conditions

post nr 1 , thread started by me :

" i partially already mentioned the first uniqueness condition before :

d f^n / d x^n sexp(slog(x) + k) > 0 for all positive integer n and all positive real k.

and probably ( i.e. if im not mistaken because of the local heat wave )this is true if and only if the following is true :

( i.e. i assume " equivalent to " )

d f^n / d k^n sexp(slog(x) + k) > 0 for all positive integer n and all positive real k. "

thread tid 484 posted on 7/29/10 title : final uniqueness condition ... probably

post nr 1 , thread started by me :

" d f^2 / d x^2 sexp(slog(x) + k) > 0 for all real x and all real k with 0 < k < Q where Q is any nonzero positive real.

assuming sexp resp slog to be C^2 of course , i 'believe' this condition implies analytic as well.

is this equivalent to d f^2 / d x^2 sexp(x) > 0 for all positive real x ?

i assume because of the substitution x = sexp(y) "

if you combine those two posts , i find it pretty clear that the idea has occured to me first.

notice that exp^[t](x) is equivalent to sexp(slog(x) + t)

despite one of those threads and this one contains mistakes , that idea is clearly mine. ( i even did a search on this forum too see if anyone else was first and looked on sci.math , mathoverflow , google and some books )

i believe my (tommy's) 2sinh method satisfies these conditions and hence it is conjectured for bases > sqrt(e) [ thus including e like mike ]

( yes these posts were made after i posted the 2sinh method - which is also by me and in fact way older than this forum ( i found it in my teenage notes ) and i mentioned that too )


thus for bases > sqrt(e) =>

d f^n / d x^n sexp(slog(x) + k) > 0 for all positive integer n and all positive real k.

d f^n / d k^n sexp(slog(x) + k) > 0 for all positive integer n and all positive real k.

d f^2 / d x^2 sexp(slog(x) + k) > 0 for all real x and all real k with 0 < k < Q where Q is any nonzero positive real.

are all ideas of me , somewhat sloppy ( i could have written positive real k e.g. ) but mine.

so basicly my opinion is that this conjecture of mike is actually a rewording of some of my conjectures.
