let f( x exp(x) ) * exp(x) * (x+1) = f(x)
then F( x exp(x) ) = F(x) + C
inversing ->
G(x+C) = G(x) * exp(G(x))
now notice G(x + n C) =
G(x) * exp(G(x)) * exp(G(x))^exp(G(x)) * ... n times.
thus exp(G(x)) ^^ n = G(x + n C) / G(x + n C - C) ( Form 1 )
and we have a solution for tetration.
now that was very briefly the idea , i know alot relates to it.
another related idea is to take the integral ;
because sexp'(x) = sexp(x) * sexp(x-1) * sexp(x-2) * ... * C2.
so sexp(x) relates to integral G(x). ( " Form 2 " not a formula yet actually :p )
now we have 2 strongly related ideas.
and keep in mind that our base needs to be bigger than eta.
for real bases > eta ; Form 1 or Form 2 might apply to one of the solutions for tetration ... ( or both sometimes !? since Derivate = prod )
i know , i know , ive only given ideas and equations , not solutions or proofs.
but still , i think it is worth consideration.
and maybe f(x) can be found by current attempts for tetration.
and G(x) might be found by inversing the ( modified ) carleman matrix of F(x)
notice also that x exp(x) has a unique real fixed point !!
i used 'x' instead of 'z' because mainly we want R > eta -> R
btw G(x) should be strictly increasing on the reals.
i hope that idea was not retarded
